Yes, I used auto-generated (fprintf, abort) stubs for similar testing in
pettycoin, where if it failed to link it would generate such stubs
for undefined symbols.

It's not a panacea, but it helps speed up rejiggin after code changes.
Generating noop stubs can actually make that process slower, as you can
get failures because you now need to do something in that stub.

Yeah, the arch trick is clever.
