Alright, that was my guess already, thx for clarifying.
For now I'm glad it still worked :)

I bet this is useful to a bunch of guys in here, so thx again for the 
My project however, uses a self made unified depends system that will build
a large number of dependencies (probably more than 70 libs) for multiple 
(linux, windows, android, osx, etc. etc.).

If I find enough time, I'll look into what's needed to pass all the 
necessary cross compile
options to build2 and might work on initial build2 support.
