If we are looking for /pthread_stubs_possible=/ that will not match.
I guess I don't understand what you are saying, or I'm confused as to
which sed you are referring to, but if I'm reading above correctly,
/pthread_stubs_possible/ does match 'pthread_stubs_possible="yes"'.

I don't understand what you are saying does not work, but what I had
above works as I had intended. If I understand the problem correctly, we
don't want configure to acknowledge that pthread_stubs is available on
our platform:
