The Qemu buildsystem expects that the cpp it is passed can be called like it were cc: it passes it the '-c' option, which is not allowed by cpp, but is allowed for cc. Fix that by overriding CPP when calling configure. Note: the target variant of Qemu does not build the affected parts (the PC-BIOS images). This is another problem that should be fixed separately.
