With HAVE_GAS_WEAKDEF undef'd, we have a large number of objc failures
with the following error:

This reference comes from thr-objc.o:
thr-objc.o
U pthread_attr_init
The header defines pthread_attr_init as follows:
static int pthread_attr_init(
pthread_attr_t *attr)
{ return(__pthread_attr_init_system(attr)); }
we have
extern __typeof(pthread_attr_init) __gthrw_pthread_attr_init __asm (""
"pthread_
attr_init");
and in __gthread_objc_init_thread_system
if (__gthrw_pthread_attr_init (&_objc_thread_attribs) == 0
&& __gthrw_pthread_attr_setdetachstate (&_objc_thread_attribs, 0xde) ==
0)
return 0;
but in the .s file, we have in __objc_init_thread_system a call
to pthread_attr_init:
.CALL ARGW0=GR
bl pthread_attr_init,%r2
.IMPORT pthread_attr_init,CODE
This shows that using __asm to create aliases to static inline function
fails.
This was with revision 106850M.
