configure.in buglet in CVS glib 1.3.1

[Valdis Kletnieks vt edu]

AIX 4.3.3 pthread.h prototypes 'pthread_attr_init' as follows:

extern int
pthread_attr_init __((pthread_attr_t *));

The attached patch allows configure to find Posix pthreads.  I added
a similar check for DCE threads just in case.  The patch should be
harmless on other machines.

(Did I do this patch before, or was that against a 1.2.X glib, or some
other package?  I'm having severe deja vu on this...)
