Feedback for ports on 12.1 stable snapshot/ppc64

[Alfredo Dal Ava Junior]

On powerpc 32 bit, try llvm90 or llvm-devel, as the support for this platform receive huge improvements recently. llvm80 support is basic and the linker doesn't generate valid code for non-static binaries.

There's a very active work[1] to move powerpc64 to llvm and to the ELF ABI v2 at same time. The powerpc 32 bit is also being worked on, but I don't have any 32 bit hardware available to test..

If you would like to give a try, please let me know and I'll prepare an experimental 32bit disc1.iso with llvm9 already included as base compiler. Would be nice to have more people involved.

Thanks,
Alfredo
