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

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

  /build/1st/tcm-2.20+TSQD/src/ed/helper.c:31·(discriminator·2)
  vs.
  /build/2/tcm-2.20+TSQD/2nd/src/ed/helper.c:31·(discriminator·2)

The attached patch to debian/rules fixes this by adding
-ffile-prefix-map to CFLAGS.

Alternately, using the default CFLAGS from dpkg-buildflags or switching
to "dh" and a recent debhelper compat level might resolve this issue.

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

Thanks for maintaining tcm!

live well,
