I managed to bisect this to SVN revision 217587 by
Martin Jambor <mjambor@suse.cz> using the attached
Dockerfile and bisect-run.sh. This was cross-compiling
from openSUSE 42.1 which happened to have most of the
build-deps easily available but should be reproducible
with a cross-compiler most places you can get wine.
