Commit 2e3646e51b2d6415549b310655df63e7e0d7a080 changed the way
the split config tree is built, but failed to also adjust fixdep
accordingly - if changing a config option from or to m, files
referencing the respective CONFIG_..._MODULE (but not the
corresponding CONFIG_...) didn't get rebuilt.
Once at it, also eliminate false dependencies due to use of
...CONFIG_... identifiers.
