libevdev will be a dependency for synaptics, evdev, and possibly the server.
it's not an X.Org project though, just an external library. it's handled by
the release.sh script because I'm lazy and don't want to copy that script
but that's as close as it'll get.  like libunwind it's just a library we
depend on and we don't need to add this to the build scripts.

having said that, if you want to add it like mesa/pixman/etc. to the build
script I'm not going to stop you :)

we've relied on mtdev for quite some time now. any distro that still doesn't
provide mtdev but still wants to ship the latest packages needs to sort that
out themselves.
