Single XML package rather than one per platform

This saves us a *lot* of copy&pasted build foo and replaces it with a couple
of config options that can be set in menuconfig.

This makes adding a new platform a much smaller operation, requiring fewer
changes that are scattered throughout the buildroot tree.
