Hmm. I'm pretty sure autoconf 2.13 set target to "NONE".

Libtool needs to know whether the helper binaries it builds need to
use a native compiler when it is configure to cross compile librarier
to a different target. If cross compiling to Windows, for example,
impgen needs to run locally for dlls built for the target host.

Looks good to me. I'm committing it now. Thanks.
