rs6000: Mirror fix for PR102347 in new builtins support

Browse Source 
Recently Kewen fixed a problem in the old builtins support where
rs6000_builtin_decl prematurely indicated that a target builtin is
unavailable.  This also needs to be done for the new builtins support, but in
this case we have to ensure the error message is still produced from the
overload support in rs6000-c.c.  Unfortunately, this is less straightforward
than it could be, because header file includes need to be adjusted to make this
happen.  Someday we'll consolidate all the builtin code in one file and this
won't have to be so ugly.
