From: Palmer Dabbelt <palmer@xxxxxxxxxxxx> I was just trying to track down a build bug with an old toolchain. Turns out Ubuntu installs old GCCs as something like riscv64-linux-gnu-gcc-10, which is a bit clunky to point the build at without a way to append a suffix to CC. There's already LLVM_SUFFIX, but nothing similar for GCC. I've split out the host and target suffixes as users probably don't have the same version of for both (unlike LLVM, where the cross compiler is likely to support the host target).
