[meta-clang][zeus][PATCH] conf/nonclangable.conf: Always build mesa with gcc

[Böszörményi Zoltán]

Building mesa (at least version 19.3.4) with clang 9.0.1 leads
to linker errors on x86/x86-64:

"undefined reference to `typeinfo for llvm::raw_pwrite_stream'"
in libvulkan_radeon.so

and

"undefined reference to `typeinfo for llvm::RTDyldMemoryManager'"
in libgallium.a.

It was reported at https://gitlab.freedesktop.org/mesa/mesa/issues/2533

It seems it is related to rtti not being enabled, at least reports
from a few years ago on forums lead to that conclusion.
But enabling rtti for clang in PACKAGECONFIG doesn't help.

Just build mesa with gcc, it fixes the linker errors.
