unix: Time to build with --gc-sections.
This actually saves "only" 6K for x86_64 build, as we're still more or less careful to #ifdef unneeded code. But relying on --gc-sections in a "lazy" manner would allow to make #ifdef'ing less pervasive (not suggested right away, but an option for the future).
