The build path is embedded in /usr/lib/libgdome.so.0.8.1:

  
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/gdome2.html

  /build/1st/gdome2-0.8.1+debian/libgdome/gdome.c:65
  vs.
  /build/2/gdome2-0.8.1+debian/2nd/libgdome/gdome.c:65


The attached patch to debian/rules fixes this by passing
-ffile-prefix-map in CFLAGS and ensuring CFLAGS is passed to configure.

Alternately, updating the packaging to use dh/debhelper at a recent
compat level would also likely fix this.


With this patch applied, gdome2 should build reproducibly on
tests.reproducible-builds.org!
