These don't need an install_name_tool thing 'cause they're loadable_modules and
not shared_libraries and loaded via dlopen instead of by dyld, yes?

[Robert Sesek, 2016/06/03 21:01:22]

The .plugin is a loadable_module found via dlopen but the .dylib is a
shared_library (but it's already set up as @loader_path).

[Nico, 2016/06/03 21:06:02]

I'd add a "# the dylib has a @loader_path that makes Chromium Framework expect
the dylib to be at the path we're moving it to" type of comment above the dylib
then
