- If you start make build as root, everything will be run as root.
Nothing new here. New is, that you can set BUILDUSER=somebody and the
unprived parts will be run as somebody.
- If you start make build with sudo, the unprived parts will be run as
the real user (meaning YOU). You can still set BUILDUSER=somebody and
the uprived parts will run as somebody.
- If you start make build as a normal user it will error out. "I'm sorry

Note that DESTDIR must be on partition with the noperm flag set for make
release to work correctly as an unprivileged user.

naddy@ pointed out that uid/gid was already taken on "important" systems.
Turns out we cannot easily recycle freed up uids/gids so settle on 51.
