Default to standalone binary build, for now

For Win32, this builds the host objects without having the libr3
functions marked as dllimport. This fixes linking the standalone
binary.

On the other hand, this breaks linking a host-only binary. For that
to work, we'll probably need separate object dirs to hold objs built
for standalone or host-only.
