Updated gfortran options.
* Removed conclude_fc.am, which was causing verbose builds. Need to investigate more, though. * Added gfortran 9 warnings and flags. This will need to be separated into other version blocks based on when the options first appeared. * The standard is now explicitly set at 2008.
