It's incredible how hard is to find an optional dependency that's needed only for some targets. I don't want to use a subdir because kamiftp needs the whole compat stuff as everything else, damn!

Trying to maintain two branches was impossible at this stage for me alone, so I'll recognize my stupidity and merge the portable branch into the main one. The repository will build using autotools.

use by default the OpenBSD mk infrastructure to build and test all the kamid components.
