The makefile will then pick the right flags for the compiler based on machine, processor and endian selection. so it'll happily build a big endian kernel with a little endian compiler. All that's really different between those compilers are the defaults. Building more different defconfigs is a better investments of CPU cycles. An issue with very large functionss for which I've posted a patch earlier today used to break makeallconfig / makeallmodconfig on MIPS. I'll sort those out but right now I just don't have the CPU cycles to regularly build such monster kernel configs. A suggested set of kernel defconfigs to test: bigsur_defconfig cavium-octeon_defconfig ip22_defconfig ip27_defconfig ip32_defconfig malta_defconfig allmodconfig These cover a huge variety of features, UP, SMP & weirdo SMP, flatmem & NUMA, 32-bit, 64-bit, little and big endian.
