Do not assume dynamic linking for musl/mips[el] targets

Browse source 
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.
