Bug#909782: libinput: please make the build reproducible

[Chris Lamb <lamby@debian.org>]

Source: libinput
Version: 1.12.0-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that libinput could not be built reproducibly.

This is due to the LIBINPUT_QUIRKS_SRCDIR config.h variable including
the absolute build path to find the test-time input file.

Patch attached that uses a relative path instead. I'm not sure upstream
will like this patch, it is provided mostly as a demonstration
ofthe problem. However perhaps it could be modified to take an
environment variable instead? I will leave this with you.
