Adjust the error return value of pthread_sigmask for !libpthread usage
Instead of returning -1, return errno on error. Catch up after the fix in libpthread by Andrew Doran in 2008 in lib/libpthread/pthread_misc.c r.1.9. It's an open question whether this function shall be used without linked in the POSIX thread library. Detected by Bruno Haible (GNU) and documented in gnulib in commit "pthread_sigmask: Avoid test failure on NetBSD 8.0. " r. 4d16a83b0c1fcb6c.
