[PATCH] pthread_sigmask: always replace when not using pthread

[Eric Blake]

On mingw, when using win32 threading, the pthread_sigmask replacement
function was not being installed.

* m4/pthread_sigmask.m4 (gl_PTHREAD_SIGMASK): Force sigprocmask
replacement when using some threading other than pthread.  Fix
logic bug.
