Actually I think that it may be safer to skip libc version regardless,
as long as we have the raw syscall test in place we are not getting any
more coverage from passing invalid address to the libc call, since
either the libc call is thin wrapper, i.e. equivalent to the syscall()
call which we already test, or it does something to the arguments, in
which case it's possible to trigger segfault, if not now in some future
libc versions.
