This is a dependency problem exposed by parallel building
(which is enabled by default with debhelper compat level 10).
I can easily reproduce this with
dpkg-buildpackage -J100
There are two ways to handle this bug:
1. fix src/Makefile.am by adding the proper dependencies to ensure
that read_config_yy.h is not used before it is built
OR
2. work around it by disabling parallel building:
- dh $@ --with systemd,autotools-dev
+ dh $@ --with systemd,autotools-dev --no-parallel
