I'm finding your examples a bit hard to follow. Can you clarify a few things:
* Did you mean have.c to just be a declaration? There is no foo in the dynamic symbol.
* What is ususe.c? Is it just use.c renamed?
* Is -o exe/libuseo a mistake -luse won't pick that up as it looks for libuse.a or libuse.so
* Please can you write a test for your patch? Look for examples in lld/ELF/tests
