Bug#1037278: afterstep: reproducible-builds: Embedded build path and usrmerge paths in example Makefile

[Vagrant Cascadian]

Source: afterstep
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath usrmerge
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build path and various binary paths are embedded in
/usr/share/doc/libafterimage-dev/examples/Makefile:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/afterstep.html

  CCFLAGS·········=·-O3·-g·-ffile-prefix-map=/build/1st/afterstep-2.2.12=.·-fstack-protector-strong ...
  vs.
  CCFLAGS·········=·-O3·-g·-ffile-prefix-map=/build/2/afterstep-2.2.12/2nd=.·-fstack-protector-strong ...

  CP»     »     =·/bin/cp
  vs.
  CP»     »     =·/usr/bin/cp

The attached patch fixes this by adjusting these values from the
debian/rules dh_compress override.

According to my local tests, with this patch applied afterstep should build
reproducibly on tests.reproducible-builds.org!

Thanks for maintaining afterstep!

live well,
  vagrant
