Re: PATCH: eliminate backtick substitution

Hi Dmitry,

    It's time to join the 1990s and replace the backtick substitutions in
    config.guess and config.sub with the $(..) command substitution

I admit I don't understand the reason behind this last change that Ben did.
What's wrong with `...`?

No question $(...) is nicer in principle, but the $(...) requirement
breaks Solaris 10 (per the last autoconf pre-release

If there is an actual technical advantage to using $(...), that's one
thing, but if it's merely to use a prettier feature, then I don't see
why that's a good enough reason to break longstanding compatibility.
