Ok. Thanks for the information. I was using
https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross.

Ok. I checked with arm-linux-gnueabi cross toolchain
and fixing these 2 errors allow us to compile the file
successfully.

No, I don't have a hardware to test these modifications.
I think this change should not lead to any breakage. But
yes it is good to test such changes. Can you please test
it for me (if you have a hardware), so that I can send v2
with fixing those errors?
