I'm trying to think where this would be useful outside your particular
situation. I'm not sure there is a lot of use.

The official way to do what you are looking to do is to mount it the other
way. On the build machine export the src/obj directories and mount them on
the target machine. Then execute your make install from the target
machine. Otherwise you run into problems like you are running into.
Especially if you're running an install as a non-root user.
