I've been curious for ages why gfortran requires using maintainer mode
for that. Nobody else uses maintainer mode for GCC development, so it
causes friction when somebody has to do changes across the whole of
gcc including gfortran parts.

If it doesn't work with a simple autoreconf then that should be fixed.
