I think you are trying to fix a problem that doesn't exit [or
insignificant].  Anyway your model will not achieve what you want.

PETSc configure behaves differently based on some options.

For eg: if '--with-cc' is specified - it uses it. But if not specified
- it guesses it [and tries a bunch of things].

So there is no way to dump a default 'value' for such things for
reuse. [The default in this case - is the absence of this option on
the configure command line]
