From 97e4591c20310425e7aca0e6712a8d9480e7744c Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 29 Mar 2013 09:30:32 +0400 Subject: [PATCH 33/35] gcc: armv4: pass fix-v4bx to linker to support EABI. The LINK_SPEC for linux gets overwritten by linux-eabi.h which means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result the option is not passed to linker when chosing march=armv4 This patch redefines this in linux-eabi.h and reinserts it for eabi defaulting toolchains. We might want to send it upstream.
