simplify "make clean" and remove unneeded lib dir from tree

the lib dir is automatically created if needed by the out-of-tree
build logic, and now that all generated files are in obj and lib,
deleting them is much simpler. using "rm -rf" is also more thorough,
as it picks up object files that were left around from source files
that no longer exist or which are no longer to be used because an
arch-specific replacement file was added or removed.
