Treat gccxml like any other compiler that pretends to be __GNUC__
(such as Intel) and test for it with __GCCXML__ and these macros that
tell you the internal GCC parser version:

  -D__GCCXML_GNUC__=4
  -D__GCCXML_GNUC_MINOR__=2
  -D__GCCXML_GNUC_PATCHLEVEL__=1

Unfortunately gccxml will not be able to dump an xml interface description
that includes __float128.
