ifconfig.sh depends on config.guess for platform guessing. It uses it to
choose between ifconfig or ip tools to configure interfaces. If
system-wide automake script is installed and local was not found, use
platform guess. It should work well on mostly any sane platform. Still
prefers local guess, but passes when if cannot find it.
