From 97e4591c20310425e7aca0e6712a8d9480e7744c Mon Sep 17 00:00:00 2001

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.
