@nasser: As @knc1 correctly guessed, mine is (mostly) statically linked, while the default one is fully dynamically linked.
Mine's also much, much newer, and much, much faster, so you won't be able to use the default one. (i.e., I built it for a reason ;p). At best it'll crash by going OOM or produce broken output, at worst it won't even run because of unsupported options.
We're talking something like 10MB here, are you really that short on storage space?

@knc1: Everything should already be stripped, FWIW

. And, yeah, libtool leaks the build rpath by default.
