main.mk introduced, lib/*.mk partially rewritten
The former toplevel Makefile is now toplevel main.mk; this change allows for multi-target, multi-arch processing in the current toplevel Makefile. As the "build" symlink semantics change quite considerably when one is doing bulk builds (several pruned builddirs might be useful for comparison), BUILDDIR is now much more likely to be recreated: the cases when it will persist are when it's either a single-image build or when the prefix hasn't changed. There are some more or less subtle bugfixes and enhancements all over the map as well. Done within 20111230..20120102 timeframe, actually...
