Do no add -no-pie on Windows

Windows binaries are always position independent
and Clang warns when trying to enable or disable
that:
```
❯ clang hello.c -pie
clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument]

❯ clang hello.c -no-pie
clang: warning: argument unused during compilation: '-no-pie' [-Wunused-command-line-argument]
```
