PATCH, v3: fix error from configure
Fri Dec 19 04:23:00 GMT 2008
On some targets, $target_thread_file can be unset (I'm not sure if that
is the right behaviour or not). This patch protects against a "unary
operator expected" error from the configure script. OK for mainline?

* acinclude.m4: Guard a variable test against an empty string.
* configure: Regenerate.
(diff against configure omitted for brevity.)
