[PATCH][BZ #14188] Allow pthread_cleanup_push to build with compilers other than gcc

[Siddhesh Poyarekar]

Hi,

As reported in bz #14188, programs using pthread_cleanup_push do not
compile cleanly with compilers that do not implement __builtin_*
functions. Attached trivial patch eliminates the __builtin_expect inside
pthread_cleanup_push macro definition in pthread.h if the compiler is
not gcc.

OK to commit?

Regards,
Siddhesh
