Bug#989965: gtk-sharp3: reproducible-builds: Example Makefiles embed build paths and binary paths

[Vagrant Cascadian]

Source: gtk-sharp3
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath usrmerge shell
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build path, several binary paths, and the value of the SHELL
variable are embedded in example Makefiles shipped in the package:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/i386/diffoscope-results/gtk-sharp3.html

  ACLOCAL·=·${SHELL}·/build/1st/gtk-sharp3-2.99.3/missing·aclocal-1.14
  vs.
  ACLOCAL·=·${SHELL}·/build/2/gtk-sharp3-2.99.3/2nd/missing·aclocal-1.14

  GREP·=·/bin/grep
  vs.
  GREP·=·/usr/bin/grep

  SHELL·=·/bin/bash
  vs.
  SHELL·=·/bin/sh

Since these values may differ with the installed system, in order to use
the example Makefiles, a person would have to regenerate them from
Makefile.am or Makefile.in, which are also provided.

The attached patch adjusts debian/gtk-sharp3-examples.install to avoid
installing the Makefiles.

If that is somehow not an option, an alternate option would be to
sanitize the Makefiles stripping the build path (or replacing with
/usr/src?), and possibly passing various variables to configure
(e.g. GREP=/bin/grep, SHELL=/bin/sh, ...).

Thanks for maintaining gtk-sharp3!

live well,
  vagrant
