I think the problem is that rustc produces .dylib on macOS rather than
it _looking_ for .dylib; the path to the .so is fully specified in the
rustc invocation of the targets that depend on it. I don't know of a way
to control the file suffix externally.

A symlink would possibly work (unless rustc refuses to load anything
other than .dylib on macOS for whatever reason), but wouldn't be very
ergonomic; you'd have to create the symlink blind or else run the build
system until it fails, then create the symlink, and then run the build
again.
