That works for system directories, but not /usr/local/lib and other
such places under user control. One could argue that we simply need
to teach old users new tricks.
I don't see how it works for /usr/local/lib anyhow. If you expect to
find the library in /usr/local/lib, but the wrong library is there,
then as far as I can see you won't find the library at all. If you
need to find it in some other directory, you will need to add a -L
option, and if you do that it will work anyhow.
Perhaps we can make gcc's multilib feature handle this somehow?

We already have --[no-]warn-mismatch that's tangentially related.
That's presumably where Jakub got the name.
That makes sense. I was thinking that --skip-mismatch was just for
archives, but technically it is for any file for which the linker
searches, so I suppose it is reasonable.
