(I meant that if a decision is made to put gfortran in base, and pkgsrc
doesn't pick it up, we can fix that.  I didn't mean to use the word
"fix" about enabling fortran in base.)

There is a basic system lib that is surely needed to be able to build
and run fortran programs and libraries.

I may have missed something, but from looking at the gcc9 plist and
trying to include everything on my gcc7 build:

As for incremental build time, I don't know.  But given we are building
the rest of gcc and llvm, I doubt it's huge.
