The build path is embedded in various binaries in /usr/bin:

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

  /usr/bin/clfdomainsplit

  /build/1st/logtools-0.13e+nmu2/clfdomainsplit.cpp:174
  vs.
  /build/2/logtools-0.13e+nmu2/2nd/clfdomainsplit.cpp:174


The attached patch fixes this by adding the -ffile-prefix-map argument
to CFLAGS in the upstream Makefile.in.

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

Thanks for maintaining logtools!

live well,
