I'm not OP but statically linking a compact libc like musl gets you just the parts of libc that you need and nothing more. This can be a lot more efficient than a dynamically linked program which has to bring in the entire bloated mess of glibc. Whether this is a benefit when you're duplicating bits of libc across every executable in your entire system is unclear to me though.
