We need to modify the build system to stop installing keymaps when told to disable them.

This appears to have been a mistake on my part when testing.

libudev: enumerate: fix NULL-deref for subsystem-matches
59bd938 
udev_device_get_subsystem() may return NULL if no subsystem could be
figured out by libudev. This might be due to OOM or if the device
disconnected between the udev_device_new() call and
udev_device_get_subsystem(). Therefore, we need to handle subsystem==NULL
safely.

Instead of testing for it in each helper, we treat subsystem==NULL as
empty subsystem in match_subsystem().

Backtrace of udev_enumerate with an input-device disconnecting in exactly
this time-frame:
