The math/big assembly for s390x and ppc64le includes instructions that the pre-built GOROOT_BOOTSTRAP compiler on their builders doesn't support (FLOGR and DIVDEU respectively).
I think updating the GOROOT_BOOTSTRAP to tip on the builders will fix the issue, but perhaps the initial Go toolchain should be built with the math_big_pure_go build tag?
