From: Robert Schwebel <r.schwebel@pengutronix.de>
Subject: zip: use $(CPP) instead of hand crafted cpp paths if specified
The configurescript tries to be intelligent and wants to guess where the
preprocessor lives. However, this badly fails in cross scenarios. We
want to use $(CPP) if the user has specified it.
