Err, it can't be __objc_force_linking that's being inlined because it is
self-recursive.  We don't inline self recursive functions last I checked.

It is more likely the case that we deferred output of the function because
of automatic inlining, then found out it was never referenced, so the function
was never output.

If that is the case, then an easy solution is to put a reference to the
function in another function or variable that is *always* output.  For
example, storing the function's address into a global (non-static variable).

Or just don't compile the target libraries with -O3 at all.  Generally I'd
prefer to see folks stick with -O2 -g instead of having everyone using their
own wild and fun CFLAGS which makes problem reproduction a *(&@#$ nightmare.
