From 7a2729ee7f5d9b9d4a0d9b83fe641a2ab03c4ee0 Mon Sep 17 00:00:00 2001
From: Joe Slater <joe.slater@windriver.com>

Subject: [PATCH 1/2] configure: use correct CPP
configure uses CPP to test that two assembler routines
can be built. Unfortunately, it will use /usr/bin/cpp
if it exists, invalidating the tests. We use the $CC
passed to configure.
Upstream-Status: Inappropriate [openembedded specific]
