The patch does more than that.  :-)

I would expect the ‘configure’ phase in (guix build gnu-build-system) to
already pass those flags, no?  (If that is the case we could keep
#:configure-flags instead of replacing the ‘configure’ phase.)

This part looks OK to me (even better if you have a pointer to an
upstream bug report or discussion.)

Thanks!
