All musl targets except mips[el] assume static linking by default. This can be confusing https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084 When the musl/mips[el] targets was [added](https://github.com/rust-lang/rust/pull/31298), dynamic linking was chosen because of binary size concerns, and probably also because libunwind [didn't](https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084/8) supported mips. Now that we have `crt-static` target-feature (the user can choose dynamic link for musl targets), and libunwind [6.0](https://github.com/llvm-mirror/libunwind/commits/release_60) add support to mips, we do not need to assume dynamic linking.
