I think the easiest way would be to have a config file with only the
required non-default options being specified and then run
"make olddefconfig" against that (or better: a copy of that in order
to avoid modifying a source from git).

I'm just writing a patch to do that for the shim config as it is nasty
to remove shim.config from my patches in case it has been modified by
the build (again) and STGit has picked it up.
