patch for configure problem with bash 2

[Dave Love]

Here's a way of fixing the problem with configure under bash 2
sourcing /dev/null.  Using a non-existent file seems a bit better to
me than creating an empty one, but there may be reason to do
otherwise.  

If the problem is fixed in the next release of autoconf, this should
probably be reverted and AC_PREREQ used in configure.in.

	* Makefile.in ($(CONFIGURE_TARGET_MODULES)): Set CONFIG_SITE to a
	non-existent file since /dev/null loses with bash 2.0/autoconf 2.12.

This patch looks OK.

The version I got was accidentally corrupted though.  One of the lines is
missing characters at the beginning.  Presumably you still have the
uncorrupted version of the patch.
