Hi Robert,
This is looking good, just one further problem:

Sadly I'm not sure it can.

Here, a hardcoded "/usr/include" in the gcc makefiles is being replaced
by ${SYSTEMHEADERS} which could be /some/other/path/include. These two
are therefore not equivalent. Did you try a "bitbake meta-toolchain"
with this patch series?
I'm sorry, because the "bitbake meta-toolchain" didn't work recently(without
these patches), I forgot to build it(just built gcc-cross and gcc-crosssdk),
I will go on working on it and send the V3 later.
Thanks

I suspect configure needs to use ${includedir} to build this path
instead of hardcoding it.
Cheers,
Richard
