post <- pkg == "runtime" && `TestUserArena` && (goarch == "ppc64" || goarch == "mips" || goarch == "mips64" || goarch == "s390x")

Example failure on linux-ppc64-sid-buildlet: https://build.golang.org/log/69bfcc3343f81bfc5c2d5a2bda3d8f8269e5b1ea

This is purely an issue on big endian machines with the allocation headers GOEXPERIMENT, and only for the user arenas feature which is also behind a GOEXPERIMENT. The fix is up for review here: https://go.dev/cl/541315.
