[Bug c/37509] New: __sync_fetch_and_xxx generates relocatable symbols

[timothy dot krause at shaw dot ca]

When __sync_fetch_and_xxx builtin functions are required to store the return
value the compiler generates an undefined reference during the link stage.

void main( void )
{
 long a=0;
 #ifndef SHOW_BUG
   __sync_fetch_and_add(&a,1); /* works just fine */
 #else
  a=__sync_fetch_and_add(&a,1); /* creates an undefined symbol */
 #endif
}
