Add an implementation of WTERMSIG() to allow nolibc programs to obtain the
signal that caused the exit of a process, and use it in WIFEXITED() since
the condition being checked there is that no signal was reported.

Thanks, but Thomas already submitted a similar one that's already queued
for 6.5 in Paul's rcu tree:
https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git/commit/?h=dev.2023.04.26b&id=8c934d4822c77818d53f5f4c948c3ace6fda1505
At least it further emphasizes the fact that the patch is needed ;-)
Thanks!
Willy
