As I just figured out, this call is supported in recent clang
versions, so IMHO: it would be better don't to break compatibility
with older compilers by this commit. It should be fairly easy to
add a new configure check whether __builtin_cpu_supports is supported
by compiler or not. I'll try to do it in libosmocore.
