This was there because pointercal-xinput were in meta-openembedded in
past; will fix it.

In fact xinput-calibrator spawns the process only if it does not find
a usable calibration; so in case you provide it, it won't start as it
can reuse the provided data.

Good; I will send the patch to move pointercal-xinput to meta-fsl-arm,
as it is where it ought to be. Please check the possibility of using
it as it'd avoid a bbappend for xorg and it will be  easier to
maintain in long term.
