clang versions prior to the current development version of 13.0.0 cannot compile s390 after commit 3abbdfde5a65 ("s390/bitops: use register pair instead of register asm") and the s390 maintainers do not intend to work around this in the kernel. Codify this in scripts/min-tool-version.sh similar to arm64 with GCC 5.1.0 so that there are no reports of broken builds.

This should probably go through the s390 tree with Masahiro's ack.
