s390-tools fails to cross build from source, because it runs bare make
without passing any cross tools. I'm attaching a patch to fix that for
your convenience. Once applying it, s390-tools can be cross built.

Helmut

Hi Helmut,

Thanks for this patch.
I have raised a PR upstream(https://github.com/ibm-s390-linux/s390-tools/pull/207)
which adds some more required changes needed for the cross-build to happen.

Thanks,
Pranav
