[svn-r8233] Purpose:
    Bug fix/code update

Description:
    Upgrade to latest version of config.guess & config.sub, which work
    correctly on Cray X1 (and may help on NEC SX-6).

    NOTE: This upgrade has _nothing_ to do with autoconf or libtool, these
    shell scripts are _not_ tied to any particular version of those tools.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    h5committest
    Cray X1
