x86_64 target missing

[AXKuhta]

You could compile x86_64 kernels with the original Proton Clang. This toolchain can't, since x86_64 target was disabled. If you were to try and compile a test .c program, it would complain:

$ clang hello_world.c
error: unable to create target: 'No available targets are compatible with triple "x86_64-unknown-linux-gnu"'
1 error generated.

I imagine this is intentional, perhaps to reduce the size or build times. Nevertheless, I would appreciate if you could add it back.
