yes thats a bug, I think you can submit a patch for that. in order to enable it fully you also need to change gcc-configure-runtime.inc
add libgfortran to RUNTIMETARGET it would be nice if both knobs were turned on or off by one switch so you don't have to do it in two
different places but such is life
