As for pthread, in Android its in libc, so this fails:

  AC_CHECK_LIB(pthread, pthread_create)

But this succeeds:

  AC_CHECK_LIB(c, pthread_create)

Bionic libc does not seem to have these though: pthread_tryjoin_np
pthread_getname_np but does seem to have pthread_setname_np.  So at this
point pth is ported and seems a better option for Android than npth.
