By default, the dynamic linking in rust binaries are limited to crt
unless a non-default flag is passed to rustc. Thus, this is effectively
static linking, albeit at an earlier stage like llvm-link(1). Rust is
not alone; golang is almost identical in this regard, by default.

ag also has next to no external dependencies at all, compared to
ripgrep's laundry list of crates it uses.
