c11/threads: resolve link issues with -O0
Add weak symbol notation for the pthread_mutexattr* symbols, thus making
the linker happy. When building with -O1 or greater the optimiser will
kick in and remove the said functions as they are dead/unreachable code.
Ideally we'll enable the optimisations locally, yet that does not seem
to work atm.
v2: Add the AX_GCC_FUNC_ATTRIBUTE([weak]) hunk in configure.
