To answer Waldemar's question, that is exactly how I worked around the problem
for gcc 4.7 and 4.8 in 2012 (see Bug 53833). That enabled me to have a
functioning gcc for ColdFire. I used it to fix broken

I suppose a different way of asking whether this should be considered a bug is
to ask what should gfortran's behavior be when libgfortran.spec is missing? Is
the correct behavior

Actually, there is: the useless movl instead of a movq of the updated address
