Library link fails on Big Sur with Fortran

[tenomoto]

The link of the library fails with --enable-f90 on macOS Big Sur because the C compiler is used to link objects that refer the names in libgfortran. Moreover with --enable-mpi the names in libmpifort are missing. In MacPorts I patched src/Makefile.in.

I apologize for my late response. I am afraid the configuration of Makefile.in is the default, because it is automatically generated by autoconf from Makefile.am. Please note that Makefile.in is rewritten every time the version is updated. I hope there is a better way.
