false

nix-repl> pkgsLLVM.buildPlatform.isStatic
false

I'm not saying only pkgsStatic is broken. But I think any cross build can be broken because we don't do:

            if head -n1 "$f" | grep -q '#!.*'; then
                # Cross-compilation hack: ensure shebangs are for the host
                echo "Rewriting $(head -n 1 $f) to #!@pythonHost@"
                sed -i "$f" -e "1 s^#!@python@^#!@pythonHost@^"
            fi
