Subject: [PATCH] blkid: --disable-libblkid to build with external libblkid
* add --disable-libblkid to switch between private (in-tree) libblkid
and public (in-system installed) library. The private version is still
enabled by default.
* add CONFIG_BUILD_FINDFS to enable/disable findfs(8) code in tune2fs.
