Convert sources/configs/$ARCH files to sources/targets/$ARCH directories. The miniconfigs are no longer stored as "here" documents, but separate files, meaning they don't need to be copied into build/temp-$ARCH and are easier to use/update/compare. The remaining data goes in a "details" file for each architecture.
