[PATCH] D60285: Make calls into the pthread library use weak symbols.

[Sterling Augustine via Phabricator via llvm-commits]

saugustine added a comment.

This is better than a no-op RWMutex because then the same binary works both when the application is multi-threaded and when it isn't. Therefore the build doesn't have to distinguish between the two cases.
