  libclc: Stop building amdgpu targets all as tahiti

It is wrong to compile as tahiti, and then treat everything
else as an alias. The IR is tainted with "target-cpu"="tahiti".
Optimizations on the libclc build can break the program, even if
the target-cpu is ultimately overridden by -mlink-builtin-bitcode.

The main risk of doing this is if mesa is still relying on finding
the subtarget suffixed bc file. As far as I can tell clover has been
removed, and rusticl only uses the spirv versions.
