It's actually not 100% correct, as this would trigger for other SIGxxx values
too,
which have the same bits set as TARGET_SIGCHLD. Given the fact that we only
support
TARGET_SIGCHLD in clone(), it would nevertheless in most cases show the correct
output.
So, probably it's best to not apply this patch it as-is.
