The official wine wiki page on Wine64 starts by saying "This port is
not yet functional", and gives a long list of problems. That would
make it seem that answer to the OP's question might be "It won't get
here until the wine people finish the port."

The package has to include the dependency libs down to the system
level - and instructions on how to install 32-bit versions of the
system library.

Since both Wine and the linuxolartor are compatability layers rather
than emulators, this shouldn't be to bad. In particular, you should be
able to install the binaries.

Yeah, I ran into that with the Perforce port. It needed a 32-bit
library, and when trying to install the port it built the 64-bit
version, then croaked because it was already installed.

Fixing the base system compiler so that '-m32' works properly would be
nice as well, and may get done as part of this.
