A somewhat educated guess is it has successfully stripped out the build
path from some things, but because the length of the build path is
different between the two builds, the padded area where the build path
would have been stored is still longer. :/

Presuming that is the case, I'm not sure how hard it would be to propose
to fix that in GCC or clang to also sanitize this, but it might be worth
exploring for Reproducible Builds as a project...

  build path	/build/1st/$pkg-$ver (not varied for stretch/buster)
  /build/2/$pkg-$ver/2nd (not varied for stretch/buster)

We also do not vary for bullseye (updated in git).

live well,
