Cross compilation to Windows, linker error (unrecognized option '-z'

[janAkali]

As I thought, it's the archlinux issue:
    
    
    gcc.options.linker %= "${gcc.options.linker} 
-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"
    
    
    Run

That's the line that was added to the `/etc/nim.cfg` by the package 
maintainers. It causes issues because `-z` flag is Linux-specific.
