Bug#1131385: libcupsfilters: please make the build reproducible

[Chris Lamb]

Source: libcupsfilters
Version: 2.1.1-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

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

This is because the testsuite generates three binaries test1284, testfilters
and testimage that get installed in the binary package... but only if 
the testsuite is run. This means that if the testsuite is skipped (i.e
via nocheck) then the package contents differ and is therefore
unreproducible.

Patch attached that deletes these particular binaries so they are never
shipped.
