From: Clément Chigot <chi...@adacore.com>
All functions but Interrupt_Wait in s-inmaop__posix are checking the
result of their syscalls with an assert. However, any return code of
sigwait different than 0 means that something went wrong for it.
>From sigwait man:
> RETURN VALUE
> On success, sigwait() returns 0. On error, it returns a
> positive error number (listed in ERRORS).

* libgnarl/s-inmaop__posix.adb: Add assert after sigwait in
Interrupt_Wait
Tested on x86_64-pc-linux-gnu, committed on master.
