Hi all,

i am using the following toolchain, from kernel.org, to build
the whole range of coldfire-based boards in u-boot.

I think in the past, in older gcc versions, likely 5.2, the build was not
failing, so seems such arithmetic functions has been removed.

Please let me know if i can help on this, or if there is any workaround.
