For powerpc, I'm about to switch it to just using clang.  riscv is
now almost ready for clang as well (I have one hack I need to do
to the kernel so lld can link it after dim@'s merges yesterday).

I probably will add some kind of WITH_GCC=yes to 'make tinderbox'
I think, but that will require untangling the mess so it can pick
per-machine_arch toolchains rather than per-cpuarch.
