[PATCH] Fix configure when /bin/sh is not bash

[Andrew S. <bi...@gm...>]

When /bin/sh used by autoconf is not bash, e.g. dash, configure
fails because it uses bash-specific equality operator "==".

Fix this problem by replacing "==" with POSIX "=" which is
sufficient for test where it is being used.
