Tree build system and OM2007.2

Didn't you see me removing all .pro files? :)
Well -- basically qmake support is gone. It was there mainly for my
personal preference (I confess, I love qmake and prefer it to autotools).

See above, it's done. autotools is it.

I agree. This is very useful!

Of course it could. Qmake can do everything autotools can do :D

Anyways, since you already worked on that, you'd be welcome to add
some top-level directory (src/target/OM-2007.2) autotools stuff that
could build everything in one run. Would you like to do that?

Cheers,

Mickey.
