Add x86 CPU check in meson.build for clang build fix

Browse source 
have_avx = cc.has_argument(avx_args)

gcc generates an error when AVX is unsupported, whereas clang only
produces a warning.

Thus, using Clang on the RISC-V platform incorrectly enables AVX file
compilation, leading to build failures.
