When -march=native is passed to host_detect_local_cpu to the backend,
it overrides all command lines after it. That means
$ gcc -march=native -march=armv8-a
is treated as
$ gcc -march=armv8-a -march=native

-march=armv8-a to

Currently -march=native selects -march=broadwell on Kaby Lake systems,
since its model numbers are missing from the switch statement. It falls
back to the default case and chooses -march=broadwell because of the
presence of the ADX instruction set.

The x86/amd64 mmintrin.h provides the _mm_empty intrinsic for the 'emms'
MMX instruction. Although ARM does not need such an instruction, we
should provide an empty _mm_empty function nonetheless for source
