I guess the number of ways to do that are just limited by our imagination:
- abusing the bell character can be quite annoying, but is broken / 
fixed in the
   linux distro's I know.
- echo "Hi there, U-boot folks over here, please STOP using _config, use 
_defconfig instead!" | write $USER
   will scare quite a few users I guess.
- sendmail + git config user.email of the OE tree should be annoying enough
- lpr ;)
- play ?
- figure out which oe recipe invoked it and patch it from u-boot ;)

And as a serious answer, no I don't know a decent method
to do it. As far as I know OE e.g. just logs to a file and only
displays its contents if an error occurred.

Afaiac, the target is just kept. Just to prevent wasting time
updating all wikis, docs etc, recipe etc. (it is not that it is a
big pile of code or something). I can add an echo of course,
but it won't be noticed by such build tools.

Jeroen
