Translate built-in include paths for sysroot.

	  gcc/
	  * Makefile.in (gcc_gxx_include_dir_add_sysroot): New.
	  (PREPROCESSOR_DEFINES): Define GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT.

	  * cppdefault.c (cpp_include_defaults): Replace hard coded "0" with
	  GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT for "add_sysroot" field.

	  * configure.ac (AC_SUBST): Add gcc_gxx_include_dir_add_sysroot to
	  control whether sysroot should be prepended to gxx include dir.

	  * configure: Regenerate.
