devel/riscv64-gcc: Add CPE information

Approved by:	portmgr (blanket)

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

Update binutils to 2.33.1

While here, convert binutils into flavors, that ease a lot maintenance
and helps cleaning out the code.

This is inspired by the same work on going on the xtoolchained gcc by jhb@

Update mpfr to 4.0.1 release and bump PORTVERSION of dependent ports.

Bring over some fixes from the other external GCC toolchain ports.

This is generally inspired by the changes in r465416 and subsequent fixes.

- Remove include-fixed headers.
- Strip /usr/local/include from the default include path.
- Use libc++ for C++ instead of libstdc++.
- Force build of a cross compiler if built on a riscv64 host.
- Bump PORTREVISION.

Chase devel/riscv64-binutils update

- Update to 7.2.0

- Update to 7.1.1
- Pet portlint

Mark the gcc crosscompiler ports as broken on various tier-2 archs.

Unfortunately neither the maintainer or I have time at the moment
to chase down all of these failures.  The "fails to package" ones
ought to be fairly easy to fix.

Discussed with:		maintainer

The output of tools like awk, date, sort, tr,... depends on the current
locale set by the user.  Add LANG=C and LC_ALL=C at the beginning of
bsd.port.mk and export them so all commands are executed with the C locale.
LC_ALL=C overrides all other LC_* variables.  LANG is used by setlocale(3)
as default value for LC_* variables, so normally it isn't used when LC_ALL
is set, but there's code out there that looks at LANG directly so it's safer
to set it as well.  The only commands not captured by this are !=
assignments before any inclusion of bsd.port.*mk.

Introduce USE_LOCALE=<locale> that adds LANG=<locale> and LC_ALL=<locale> to
CONFIGURE_ENV and MAKE_ENV so upstream build systems can be executed with a
different locale (e.g. USE_LOCALE=en_US.UTF-8).
