            Log:
            Only build CC variant for aarch64 and x86_64

Currently we attempt to build it on riscv64 too, but that
fails with

  grub-mkimage: error: cannot open `grub-core/backtrace.mod':
  No such file or directory.

Trying to get CC running on riscv64 is premature anyway.
Explicitly limit the CC build to aarch64 and x86_64.
