You can't do that for ELF, you have no idea what libraries symbols are
meant to come from. The NEEDED entries in a binary are how the loader
knows what's needed and what's not, as the name implies. There's no way
to strip these entries once the binary has been built (except taking
them away one at a time and seeing if anything breaks ...) so it's
better if the compiler/linker does it.
