Shoot. The GTHREAD_USE_WEAK and SUPPORTS_WEAK macros are used from <gthr.h>, and it is up to each library to define them appropriately. I don’t know how my regtesting came up positive, though…

Installed the attached patch to fix it: we retain the old macros for gthr.h’s sake, and use the new one internally. Testsuite clean so far on x86_64-linux.
