[PATCH] Don't use ./tmp0 for site.exp generation

[Richard Guenther <rguenther at suse dot de>]

This patch sits in all my development trees because delta uses
tmp? named directories for storing intermediate files.  This causes
a make check to fail.

Maybe there is an even better way to create a truly temporary file
name (that is even portable), but the following patch simply avoids
using tmp0 in favor of tmpDG.

Bootstrap and regtest running on x86_64-unknown-linux-gnu (not that
I expect any problems).

Ok for trunk?

Thanks,
Richard.

	* Makefile.in (site.exp): Do not use tmp0 but tmpDG as temporary
	file name.
