sigwait: Do not fail with EINTR and return error code [BZ #22478]
Since
commit 8b0e795aaa445e9167aa07b282c5720b35342c07
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Wed Nov 1 11:49:05 2017 -0200
Simplify Linux sig{timed}wait{info} implementations
sigwait can fail with EINTR. Applications do not expect that, and the
error code is not documented in POSIX or the manual pages.
This commit restores the previous behavior by retrying the system call
on EINTR. It also returns the error code, not -1, on the remaing
errors.
