lang/rust: fix build on powerpc64 elfv2

After upgrade to LLVM 10, core in stage 1 fails to compile (no clear reason,
rustc crashes):
pid 26828 (rustc), jid 0, uid 0: exited on signal 11 (core dumped)

Compilation with GCC works fine, so switch to GCC for the time being.

lang/rust-nightly: Update to 1.43.0.20200306

libgit2-sys is now based on libgit2 0.99.0.  While 0.99.0 is supposed
to be API compatible with 0.28, it has not yet been updated in the
ports tree and the git2 crate now make use of some of the new
function return values.  Stop relying on system libgit2 and use the
bundled one.  Upstream does not make any guarantees about system
libgit2 support in the first place.

lang/rust: Add COMPAT_FREEBSD11 canary

This attempts to provide a nicer error message for the subset of
users who build their own kernels without COMPAT_FREEBSD11 and then
attempt to build lang/rust.  The Rust ecosystem currently uses
pre-ino64 syscalls, so building lang/rust without COMPAT_FREEBSD11
is not going to work.

The error message for this is non-obvious and there is a new bug
for this at least every 1-2 months.  Hopefully this will improve
the situation a little.

Cargo and Gecko ports are similarly affected, so add the pre-build
check to them too.

lang/rust, Mk/Uses/cargo.mk: Drop gmake build dependency for backtrace-sys

The backtrace-sys crate no longer needs gmake since 0.1.20.
sysutils/flowgger still uses backtrace-sys-0.1.14.  Since it is the
only USES=cargo port left that needs it, move the gmake dependency
directly to it instead.

lang/rust currently has backtrace-sys-0.1.30.  It also vendors
jemalloc-sys (which also needs gmake to build) but it is hidden
behind rustc's jemalloc feature which we do not currently activate.
It should be safe to remove gmake in lang/rust too.

lang/rust: Update to 1.29.0

Release notes:
* https://blog.rust-lang.org/2018/07/20/Rust-1.27.2.html

Up to and including Rust 1.27.x, the Rust build system shelled out to
a configure script to detect the presence and usability of libunwind.
Since Rust 1.28.0, it's using a static result in a `build.rs` file and
expects libunwind to be used. It was not the case on FreeBSD so far, so
we need a patch to this `build.rs` to disable that. We still need to
study if the FreeBSD port should use libunwind and what to do with this
patch. But this problem prevented the update to Rust 1.28.0 already, so
enough delay.

lang/rust: Udpate checksums in libgit2-sys/.cargo-checksum.json

It was part of the initial patch from Charlie Li to support LibreSSL
2.7. However, I misread it and though he was only removing bits
which were not needed anymore (updating checksums for openssl and
openssl-sys).

Now, we update all three: libgit2-sys, openssl and openssl-sys.

Rust is marked as broken on aarch64. The reason is the bootstrap
compiler crashes currently. See PR 228892 which tracks the issue.

A patch for aarch64 is still included. It fixes the sign for unqualified
C char. This patch still needs to be upstream, but for that, the
compiler needs to work again first.

lang/rust: Add `make makesum-all-archs` target

It is a helper to ease the generation of the `distinfo` file for all the
architectures we support. It avoids the manual commands.

lang/rust: Update to 1.26.0

The announcement is available on Rust blog:
https://blog.rust-lang.org/2018/05/10/Rust-1.26.html

Rust 1.25.0, used as the bootstrap compiler, contains the patch from
bdrewery@ to use the compat (non-ino64) symbols on FreeBSD 12-CURRENT.
Therefore, we don't need `old_fstat.c` and the associated machinery in
the `Makefile` anymore.

Update to 1.25.0.

- The ABI patch is no longer needed on head due to fixes being upstreamed
  to use the pre-ino64 symbols.  The ABI patch is still needed for the
  bootstrap but should be removable for 1.26.0 if it uses beta 2018-03-18.

lang/rust: Update to 1.24.1

The announcement is available on Rust blog:
https://blog.rust-lang.org/2018/03/01/Rust-1.24.1.html

There is a compilation error when it builds `clippy-driver` and `miri`
but it apparently doesn't affect the result. There are probably optional
tools/dependencies.

Update rust-nightly to 2018-03-21.

The ABI patch and bootstrap patching are no longer needed on head after
fixes fully upstreamed in https://github.com/rust-lang/rust/issues/42681.

Fix WITH_CCACHE_BUILD when using Poudriere's ccache-memcached support.

- Fix kevent on head by binding to the old ABI symbol version.
- Add some context in the patches for where they came from.  They need to be
  in 1 patch due to needing to use the .orig file for fixing up checksums.

Support WITH_CCACHE_BUILD for bundled LLVM

Unbreak on i386/amd64 and update to 1.25.0-2018-02-19

- Stop using git to build as it is unmaintainable due to submodules,
  but more importantly because src/vendor is no longer bundled.  Just
  fetch the source already generated that has all dependencies bundled.
  It may be a bit slower to get updates but is far more maintainable.
- Copy all patches to lang/rust-nightly/files since they may not always
  apply exactly between both versions.
- Add in patch for llvm-config getting -lexecinfo wrong, this is in
  review with LLVM at https://reviews.llvm.org/D42702.
- Bring in other random updates from lang/rust.

No need to actually recompress rust-std, libarchive does the right thing

Newer versions (rust-nightly 2018-02-19) pack multiple .o files into
libstd.  We only need to patch one of them.

The suffix of that file changed in recent versions of Rust and it's
changing again between Rust 1.23.0 and 1.24.0. So let's grep the
filename from the list of files contained in the ar archive.

lang/rust: Skip `.cargo-checksum.json` update when it's missing

Currently we need to update `.cargo-checksum.json` in several patched
crates. But those crates are missing from the sources if they come from
GitHub instead of a proper released source archive. This change makes
`post-patch` and `do-configure` recipes fine in both cases.

lang/rust: Always replace bootstrap versions in `stage0.txt`

This simplifies the `Makefile`. The condition was fragile anyway because
it was based solely on the Makefile and not the actual content of
`stage0.txt`.

lang/rust: Find libstd's suffix at runtime

... instead of hard-coding all values in the Makefile.

This eases the update of Rust.

lang/rust: Disable "omit frame pointers"

Before the patch, the default behavior of the compiler was to omit frame
pointers. However, even though it looks fine for the code produced
by the compiler, the compiler itself was broken. When there was a
compilation error, rustc panics to report that error. While handling
that panic, it tries to unwind the stack but fails to do so, which
results in an abort(3).

Here is an example:

    $ rustc hello.rs
    error: invalid reference to argument `0` (no arguments given)
     --> hello.rs:2:5

lang/rust: avoid LLVM targeting SSE2 on i386 by default

This may help ports like textproc/ripgrep to run on old hardware.
Rust itself still requires SSE2 until bootstrap is regenerated.
