one of the things that attracted me to FreeBSD was the fact that I could 
cross-compile. I always, till now, used a RELENG as a base (solid? :-) to
build CURRENT, but now, so close to releases, I decided to try the other way,
just before upgrading.

So now I have some questions:
	- Is documented != supported?
	- is building on a RELENG for CURRRENT ok?
