Fix build against older pthreads implementations

Older pthreads implementations like glibc NPTL prior to version 2.12, and
uClibc linuxthreads (both), need _XOPEN_SOURCE to expose
pthread_mutexattr_settype() and THREAD_MUTEX_DEFAULT. The value 600 (SuSv3,
POSIX.1-2001) is equivalent to _POSIX_C_SOURCE 200112L.

Fixes the following build error:

  CC       compat.lo
compat.c: In function 'p11_mutex_init':
