From fc5c889131ff6270e1028cc7edd87e7f10a7da6d Mon Sep 17 00:00:00 2001
From: Romain Naour <romain.naour@openwide.fr>
Date: Thu, 22 Jan 2015 15:21:31 +0100
Subject: [PATCH 2/6] configure: Don't use host CPP
CPP is redefined if a cpp binary (/lib/cpp) is found on the host.
Use the CPP="${CC} -E" allows to pass the following checks:
Check if we can use asm code (for -DASMV)
Check if compiler generates underlines (for -DASM_CRC)
Signed-off-by: Romain Naour <romain.naour@openwide.fr>
