I think in general it's actually better to have a wrapper script or Makefile around Buildroot, because that gives a lot more flexibility. Still, this proposal is symmetrical with the post-image script. And the overhead is negligible. So I applied to master after all.

We introduce the concept of a pre-build script that works similar to the already existing post-build and post-image scripts. The pre-build script(s) are executed before the build commences. This allows a user to run some preperatory tasks prior to the build.
