On Solaris 11, I see many warnings:
gllib/glthread/thread.h:236:27: warning: cast to pointer from integer of
different size [-Wint-to-pointer-cast]
I wouldn't care much about 1 warning, but these are many.
This patch fixes them.

thread: Avoid compiler warnings on Solaris.
* lib/glthread/thread.h: Include <stdint.h>.
(gl_thread_self_pointer): Do the cast from pthread_t to 'void *' via
intptr_t.
* modules/thread (Depends-on): Add stdint.
