Hi Ross,

I just found that when build with eudev, the files will be installed
to /lib64/udev, and when build with systemd, they will be inistalled
to /lib/udev, so I think that they are OK. They use
"pkg-config --variable=udevdir udev" to find udev dir, while systemd
is /lib/udev and eudev is /lib64/eudev.

The one which has problem is libinput which installs /usr/lib/udev or
/usr/lib64/udev, this in incorrect. Another problem is that systemd
doesn't install udev.pc.

I think that the fix for btrfs-tools is correct. I will send a V2 with
another 2 fixes.
