[PATCH 2/2] configure: print info about required gmime 2.4 or 2.6 versions

[Tomi Ollila]

In case required gmime (2.4 or 2.6) version if not found print information
about both alternatives (and currently minimal 2.6 version that is needed).
---

I'm not entirely happy about the implementation but I would be less happy
to write static message that has the same spesific version information in
second place (third if comments are counted).
