From af4c3ae3990bb5a2f0a53c7112c9d7696a3cab95 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Thu, 21 Mar 2013 12:22:06 +0530 Subject: [PATCH] ARC: [build] silence make defconfig warnings with host gcc 4.7 We do cross compiles for ARC Linux. With gcc 4.7, a make defconfig spews out the following: ------------------->8-------------------------- make ARCH=arc defconfig gcc: error: unrecognized command line option '-marc600' gcc: error: unrecognized command line option '-mA7' gcc: error: unrecognized command line option '-mno-sdata' gcc: error: unrecognized command line option '-mno-mpy' *** Default configuration is based on 'fpga_defconfig' ------------------->8-------------------------- This apparently is coming from LIBGCC line - which is strange to be invoked for defconfig generation.
