	* libcsupport/Makefile.am, libcsupport/preinstall.am: Reflect change
	above.
	* libcsupport/src/gxx_wrappers.c: Include <rtems/gxx_wrappers.h>.  Use
	_Internal_error_Occurred() instead of rtems_panic().
	* score/include/rtems/score/interr.h: Added
	INTERNAL_ERROR_GXX_KEY_ADD_FAILED and
	INTERNAL_ERROR_GXX_MUTEX_INIT_FAILED.
