Bug#1021512: yersinia: reproducible-builds: build path embedded in /usr/bin/yersinia

[Vagrant Cascadian]

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

The build path is embedded in /usr/bin/yersinia:

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

  /build/1st/yersinia-0.8.2/src/yersinia.c:104
  vs.
  /build/2/yersinia-0.8.2/2nd/src/yersinia.c:104

The attached patch to debian/rules fixes this by passing CFLAGS directly
to make, and adding -ffile-prefix-map to CFLAGS to avoid embedding build
paths.

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

Thanks for maintaining yersinia!

live well,
  vagrant
