Subject: [PATCH 8/9] Fix invalid sigprocmask call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The POSIX document says
The pthread_sigmask() and sigprocmask() functions shall fail if:
[EINVAL]
The value of the how argument is not equal to one of the defined values.
and this is how musl-libc is currently doing. Fix the call to be safe
and correct

gdb/ChangeLog:
2017-03-24 Yousong Zhou <yszhou4tech@gmail.com>
* common/signals-state-save-restore.c (save_original_signals_state):
Fix invalid sigprocmask call.
