This looks good to me.

OK to commit if you tested the UNSUPPORTED case by either hacking
out the syscall wrapper to return ENOSYS or running on a system
that didn't have sendmmsg.

I think hakcing sysdeps/unix/sysv/linux/sendmmsg.c to return ENOSYS,
recompile, recheck, should be enough to test UNSUPPORTED was wired
up properly.

Cheers,
Carlos.
