INSTALL and buildprep

Or maybe only tell me about the packages needed for a specific configuration.

There is a chicken/egg problem with waf.  It won't configure unless the 
header files and libraries are available.

There is also the cross build area.  Tell me what I need to build for a 
specified environment.

Does buildbot have a crossbuild case?  Say building for a Raspberry Pi on an 
Intel platform.
