What about adding a new Kconfig option like:

    config BR2_BUILD_INFRA_STEP_SCRIPT
        bool "script to run before and after each step"
        help
          Buildroot will call this script before executing any single
          step in the build process. The arguments to this script are:
              $1: either "pre" or "post", resp. meaning "before" or
                  "after" the step
              $2: name of the package
              $3: version of the package
              $4: action to be done

          Leave empty (the default) to not run any script.

It would then be the responsibility of the user to provide such a
script. We could provide a simple script that just do this logging as an
example.
