check for gfortran before checking for g77

[kamaraju kusumanchi]

While configuring apr-1.3.3, I realized that the configure script
checks for g77 and not for gfortran. The development of g77 has
stopped and is now replaced by gfortran. gfortran works well on both
Fortran 90, Fortran 77 programs. Would it be possible to add a check
for gfortran before checking for g77?

thanks
