The new building rules for x86_64 target in marshallow
have by default ARCH_X86_HAVE_SSE4_1 := true
This triggered a linking issue when building gallium_dri,
because libmesa_st_mesa is used as static library,
but the SSE4.1 optimizations are only built with libmesa_dricore.
This solution allows to avoid the linking issue and
to optimize libmesa_st_mesa with SSE4.1 functions,
when applicable for x86_86 target of marshmallow.
