Adhemerval Zanella Dec. 29, 2017, 2:58 p.m.
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.
