Hi Atafford,
I do apologise for troubling you, we have updated the make.cross,
you could use "GCC_VERSION=6.0.0 make.cross ARCH=openrisc" to reproduce.
Best Regards,
Rong Chen

Again, in plain text mode:
Did something change with the compiler setup? The error here says gcc
6.0.0. however the version in the make.cross tool is 5.4.0, which is
strange. Fyi, We have binaries for 7.2.0 and 9.x which can be used.
Also our toolchain is all upstream as of last week.
