Cross platform compilation error for Zmpl templates

[NPatel10]

I am having problem cross compiling Zmpl from one platform (windows) to another (x86_64-linux-gnu).

Steps to reproduce:

1. Create a zmpl project with some zmpl template.
2. use zig build install -Dtarget=x86_64-linux-gnu to compile the zig code. this will generate error.

Expected result

• Above command should run without any error.

One possible solution to this problem is using host target for manifest executable. So in build.zig instead of

const manifest_exe = b.addExecutable(.{
      .name = "manifest",
      .root_source_file = b.path("src/manifest/main.zig"),
      .target = target,
      .optimize = optimize,
      .use_llvm = use_llvm,
});

using below code resolves issue

const manifest_exe = b.addExecutable(.{
      .name = "manifest",
      .root_source_file = b.path("src/manifest/main.zig"),
      .target = b.graph.host, // <------------------------- Changed this
      .optimize = optimize,
      .use_llvm = use_llvm,
});

This works because manifest executable runs during build process to convert zmpl templates to zig functions. There for it's target should always be native.
