If no machine specific formfactor is found, the formfactor config defaults
to HAVE_TOUCHSCREEN=1. The result is for the matchbox session to disable
the cursor. This can lead to a lot of churn sorting out why the cursor doesn't
appear: xorg bug, xorg driver bug, kernel drm driver bug, kms bug, many
of which appear when searching for invisible cursor on the web.
On the other hand, if a cursor appears on a touchscreen device, one is much
more likely to reach a correct conclusion: "I need to set HAVE_TOUCHSCREEN=1
in my custom machine formfactor config". Which likely exists or is needed for
other formfactor specific things such as dpi, screen size, rotation, etc.
