Rollup of fixes since the 9.0.0 release.

- Change the default -march for i386 from i486 to i586.  This avoids
  the need for libatomics and had been the defacto default for some
  time. [0]

- Add -m(no)-spe to clang. (powerpc)

- Deduce MIPS specific ELF header flags from `emulation`. (mips)

- Fix a variety of assertions and compile/link errors including crashes
  with CPUTYPE=haswell. [1]

- Switch back to https for downloads. [2]

The new patches were initially committed to FreeBSD src by dim@.
