Rollup merge of rust-lang#160620 - mati865:no-no-pie-windows, r=bjorn3

Do not pass `-no-pie` on Windows

The warning can be seen with a simple example:
```
❯ cargo new /tmp/hello -q
❯ cargo rustc --target x86_64-pc-windows-gnullvm -q -- -C target-feature=+crt-static
warning: linker stderr: clang: argument unused during compilation: '-no-pie' [-Wunused-command-line-argument]
  |
  = note: `#[warn(linker_messages)]` on by default
```
