These two patches enable the current OSELAS.Toolchain-2012.12 to generate a
armv4 eabi toolchain. armv4 devices (like strongarm or fa526) have no thumb
support and do not understand the BX intrinsic.
The added patch enables the GCC to save the target machine and instruct the
linker later on to replace BX by MOV or other matching intrinsics.

+Subject: [PATCH] arm:eabi: pass --fix-v4bx to ld
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From https://raw.github.com/openembedded/oe-core/master/meta/recipes-devtools/gcc/gcc-4.7/gcc-armv4-pass-fix-v4bx-to-ld.patch
+
+---8<---
+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
+
+Upstream-Status: Pending

This toolchain has libc for armv4 without thumb support (namely some older
stongarm and fa526 processor).
