[rb-general] Need a tutorial on NT_GNU_BUILD_ID

[anatoly techtonik]

Hi.

I am trying to see why Inkscape build is not reproducible.
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/inkscape.html
It seems like there is problem with NT_GNU_BUILD_ID, but in
order to fix that it would be nice to understand where it comes
from, how it is being calculated. see the list of variables that
participate in the formula and recipe how to fix them.

Currently there are no docs about it:
