There's a report that btrfs-find-root does not work as built-in tool in
btrfs.box, while it's advertised in the help:
$ ./btrfs.box help --box
Standalone tools built-in in the busybox style:
- mkfs.btrfs
- btrfs-image
- btrfs-convert
- btrfstune
- btrfs-find-root
Add the support as it might be useful tool sometimes. In the future the
command should be moved to e.g. inspect-internal or rescue.
Issue: #648

Build several standalone tools into one binary and switch the function
by name (symlink or hardlink).
* btrfs
* mkfs.btrfs
* btrfs-image
* btrfs-convert
* btrfstune
The static target is also supported. The name of resulting boxed
binaries is btrfs.box and btrfs.box.static . All the binaries can be
built at the same time without prior configuration.

1361696 mkfs.btrfs.static
So the shared 900K binary saves ~2M, or ~5.7M for static build.
