rs6000: AIX long double builtins for 64 bit long double.
When long doubles are 64 bit, the AIX C library overrides the definitions
but GCC builtins point to 128 bit names. This patch overrides the
builtins for fmodl, frexpl, ldexpl and modfl to refer to the 64 bit symbols.

* config/rs6000/rs6000-call.c (rs6000_init_builtins): Override explicit
for fmodl, frexpl, ldexpl and modfl builtins.
