Not sure.  My only guess would be maybe autoconf wants FC to be defined. 
 According to this:

http://www.hep.by/gnu/autoconf/Fortran-Compiler.html

FC can be Fortran 77, 90 or 95.  But also the way to make the definition 
seems slightly different than saying FC=$F77.  Perhaps the documentation 
at the above link makes more sense to you since you are working on the 
make files right now.
