IIRC, the only reason we had the "compatible with..." part of the message in other cases is because some system configuration scripts expected some particular string to be present in order to correctly identify the llvm tool as `strip` or `objcopy` or whatever. If you aren't under the same constraints here, I'd drop this phrase.
