Subject: Reorganize kernel configs - target/linux/*/config is now a directory.
 ./config/default will replace the old config and config-diff (format is like
 config-diff, the full kernel config is no longer kept in the build system)
 This commit removes all the kernel config stuff, the next one will add the
 replacement - there's no way to do this atomically with svn.
