FortranCInterface: Support '=' in language flags 

The commit "FortranCInterface: Honor language flags in checks" taught
the FortranCInterface module to pass C and Fortran flags into its
detection and verification checks.  We improve on the change to allow
the '=' character in the language flags.  This requires passing the
cache entry type with the -D options.
