In another patch ("tests: Use the normal yank code instead of stubs in 
relevant tests"), Lukas now changed the tests to always explicitly link 
against the real yank.c code. That makes me wonder whether we need the yank 
stubs at all ... it's not that much code after all, and it's very much 
self-contained without references to other files, so I think it should also 
be ok if we simply always keep it in the utils library and ditch the stubs?
