Not tying ourselves at all. This just gives users who install gcc manually with
the ./configure process a default to use and only if they are using the download
prerequisites script which is optional. Distributions can still provide multiple
choices with package managers.
The final tie is at link time where a user may specify any compatible library
they choose. We do have a base of users who do not use package managers by the
way. So the goal is a minimal installation of a fully functional Fortran.
