This commit which is marged upsteem seams to solves the issue.
https://github.com/OpenLightingProject/ola/commit/3eaed8c98d75efcff3b8e4f893b03634308156c3
I have tests it on my local boards and it builds successfully for mips, mipsel
and mips64el.
A patch which contains these changes is attached.
Could you please include this patch.
Regards,
Radovan
