Hi Geert,

Thansk for the report.  I have updated the toolchain that is pointed to
by make.cross [1] a few weeks back.  Fengguang and I updated the
make.cross tool which the build robot's point to a late tool chain [2],
what are you using?

If you can update to the or1k-linux-5.4.0-20170218 toolchain it should
fix these issues.  Let me know if you have any questions.

Also, you may need a late version of QEMU if you are doing testing with
QEMU I had patched a few things there as well.

Also, there were a few more warnings pointed out by a make allmodconfig
test build.  I have some patches I am about to send out for review with
fix those things up.
