This might actually be the best solution. OS X has a similar disease
but some trolling of the ld man page suggests that -dead_strip_dylibs
might work there. Taking this path would amount to assuming that all
linkers we care about either have an equivalent switch or don't link
unrequired libraries in the first place.

I'll do some experimenting...
