This libgo patch by Paul Murphy ensures that openat always uses the
variadic libc wrapper.  On powerpc64le, not using the wrapper caused a
failure in TestUnshareUidGidMapping due to stack corruption which
resulted in a bogus execve syscall.  This fixes GCC PR 98610.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
