I guess we need autoreconf because we get an extract of the repository,
right? Please add a little note about it, it is not obvious at first
sight.

lockdev is introduced only in a subsequent patch. This should have been
reversed: lockdev first, then libcec.

Although not strictly required, I'd like an explicit --disable-rpi in
the case rpi-userland is not available.

(In my twisted mind, I was imediately thinking of using Buildroot on an
RPi that does have rpi-userland, but would not want it in my generated
image, so would not like to pick the system one. Yes, I'm weird.:-] )
