Hi Thomas - the following patch fixes this and also avoid duplicating
some options on the gcc command line.

# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.1296.61.1 -> 1.1296.61.2
# scripts/Makefile.lib 1.22 -> 1.23
# Makefile 1.435 -> 1.436
#
# The following is the BitKeeper ChangeSet Log
# 03/10/12 sam@mars.ravnborg.org 1.1296.61.2
# kbuild: Fix make O=../build xconfig
#
# Compilation of qconf required -I path to qt. kbuild invalidated the
# path to qt by prefixing it with $(srctree). No longer prefix absolute paths.
# Also do not duplicate CPPFLAGS. Previously it was appended twice to CFLAGS
