actually, it is quite simple: just (re)generate a file which you can
compile and link to your executable. That is how gits version work:
$ git version
git version 1.5.3.4.229.ga321c1
this ga321c1 is the commit (no one knows what the "g" stands for, but
the rest is plain value of HEAD at the moment of compilation).
Put the generated string in your image in a greppable/identable form
and you are set: the commit identifies uniquely the whole build tree
(assuming your build tree _can_ be identified. It not given for most
commercial projects I am familiar with).
