Buildsys primer

[Linus Walleij]

Is there some document on what is actually set up and happening on the 
other end of the build system?

I am more looking into knowing what versions of compiler and accompanying 
tools may be expected to carry out the compilation... I would guess a 
standard FC-X / devel base distribution to do the packaging for respective 
target but what do I know. Where do you go reading?
