Perhaps we'll retain PETSC_DIR/makefile as-is and have a wrapper over
gmakefile - similar to the one we currently have over cmake's
gmakefile?

Since this is not critical for user builds - I'm not concerned about
supporting these dependencies on windows [via win32fe].

However I'll have to recheck FC_MODULE_OUTPUT_FLAG stuff [revert this
test back to raise-error].

Also we'll have to check the shared targets [on other non-linux OSes?]

I'm not sure if there are any other issues to check..
