On -current, gcc was removed from base, so the only choices left are to
use clang in base and gcc from ports.

On stable/12 and stable/11, clang is only enabled for aarch64, amd64,
arm, i386 and riscv (on 12). You will have to use base gcc or gcc from ports.

Import what? If you mean clang/llvm 11, I will MFC it in about 6 weeks,
provided the ports people don't kill me first. ;-)

If you want to attempt building 12-stable with clang, you will probably
have to use an external toolchain for bootstrapping, and set
MK_CLANG=yes, MK_CLANG_BOOTSTRAP=yes and MK_CLANG_IS_CC=yes in your
src.conf, before building world. Then you should be able toinstall that
world into your poudriere jail.

Won't what? Work, compile, install? I am unsure if there are any
pre-built packages available for mips64, but I would look for them, if
at all possible.
