After some research it appears this needs to be solved on the users end. Although if we could change upstream to make this more convenient that would be great.
I ended up with a per binary crate build.rs exactly the same as the one at: https://github.com/japaric/f3/blob/b40415b4c4f7e76bdf27dcb570bf961c75cb707b/build.rs
This solves my problem so feel free to close this issue, or it can be kept open if there is a better solution that could be done upstream.

I think your conclusion is basically right: we don't control where the linker gets the memory.x
from, it searches its own search path, which starts with the current working directory (the workspace or crate if not in a workspace) and then goes to the OUT_DIR
. When users are building a not-in-workspace crate or have one memory.x
shared by all crates in a workspace, no build.rs
script is required, but otherwise one such as your example is.
The only thing we've discussed that could be a nicer solution is to revamp the linker script entirely so that it's generated at build time by a function inside the user's build.rs
which could then also specify other sections and so forth, but that's some way off.
Thanks for reporting the issue and your conclusions!
