I pulled the list of platforms which define these from rust-lang/libc. Although nix doesn't support Haiku or Hermit, there are other cfg blocks which reference them in nix, so I included them here.

I omitted newlib and VxWorks, as nix doesn't currently have any cfg blocks for them.

target_os = "netbsd", target_os = "openbsd"))]
