This patch adds a default pthreadtypes-arch.h based on default thread definitions from mutex-internal.h, rwlock-internal.h, thread-shared-types.h, and pthreadtypes.h. The idea is to simpify new ports inclusion and an override is required only if the architecture require some different alignment requirement. * sysdeps/nptl/bits/pthreadtypes-arch.h: New file.
