Excerpt of the failing build log

In wine 1.2, building a shared WoW64 build worked nicely using the method
described on the wiki (http://wiki.winehq.org/Wine64). In wine 1.3.0,
--enable-win64 causes trouble:

winebuild: winebuild: Unable to create output file
'dlls/activeds/libactiveds.def'

git bisect brought forward commit b0e48e1e2bb285fe9dd31c6c77505f0b51819178 as
the culprit.

This is appears to be a regression. I'm attaching a patch to revert the
regression and an excerpt of the build log of where it fails.
