Currently the default (in GNU Make anyway) for FC is set to f77. This makes it so that

FC ?= gfortran

never works (although if FC is set in the environment or on the command line this will work). Something like

ifeq ($(FC), f77)
    FC = gfortran 
endif

would work to replace f77 (since we do not support it anyway) but this really should happen above any variables the user sets.

Decided with @rjleveque to modify the Makefile.common and the local Makefiles to not include the FC variable and set FC = gfortran in Makefile.common if FC = f77.
