Yep, sorry about that -- we revamped the Fortran support in v1.7 and beyond such that the following are used with configure:

v1.6.x and earlier: F77, FFLAGS, FC, FCFLAGS
v1.7.0 and later: FC, FCFLAGS

I.e., we consolidated down to one Fortran compiler for v1.7.0 and later (and similarly deprecated mpif77 and mpif90 -- mpifort is now preferred in v1.7.0 and layer).
