[Buildroot] [PATCH] package/qemu: fix build of host variant

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.
