I think we should make --preserve-dup-deps at least collapse the same
library listed consecutively with a single instance of that library,
i.e., "-lm -lm -lm ... -lm" would become just "-lm".  This would still
solve the problem that --preserve-dup-deps is meant to address.

Patches _not_ forthcoming, but please take this idea and run with it.
