include/generated/compile.h is autogenerated, but arch/mips/boot/start.o
does not have a dependency on that file, so depending on the number of
cores you have it might or might not exist when you compile start.S.
Just try building barebox again when it failed, it should work the
second time. The patch you post may work by accident, but is no proper
fix for this problem. Unfortunately I haven't found a working solution
yet other than removing UTS_VERSION from start.S
