I can tell you from my experience that mrustc's cargo implementation is
extremely limited and does only the bare minimum in terms of
functionality.  It already needs some help to work with static
libraries, but I'd really like to minimize the work that needs to be
done on it since it's not lovely code, and using a standard layout is
going to help with minimizing the necessary changes.  I will admit that
I haven't tested using a non-standard layout, but I fully expect it will
not work based on my experience of the codebase.

For what it's worth, it looks like mrustc supports non-standard layout
just fine[1], and that's not totally surprising, because the rustc codebase
used to use non-standard layouts a lot (although that's not true
anymore)
