Right. Ignore this patch, I forgot that I had local patches in OpenEmbedded which should have been forward ported correctly.

[PATCH] Cpp: honor sysroot location
Currently, if the gcc toolchain is relocated and installed from shared state
cache, then you try and compile
preprocessed source (.i or .ii files), the compiler will try and access the
builtin sysroot location
rather than the --sysroot option specified on the commandline. If access to
that directory is
permission denied (unreadable), gcc will error.
This happens when ccache is in use due to the fact it uses preprocessed source
files.
The fix below adds %I to the cpp-output spec macro so the default substitutions
for -iprefix,
-isystem, -isysroot happen and the correct sysroot is used.

[PATCH] 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.
