Code Review
This pull request effectively fixes a dynamic linking issue when using zig cc with autotools by correctly setting the LD environment variable. The approach of extending the zig toolchain with more tools like ld.lld is sound and makes the toolchain more robust.
Regarding your questions:
- The way you've defined the new toolsets (e.g.,
ld.lld,lld-link) is functionally correct for xmake. While these are not standard toolkinds and might produce "unknown toolkind" warnings in verbose mode, this is an acceptable way to extend a toolchain for specific needs. The ideal long-term solution would be to register these toolkinds in xmake's core, but that's beyond the scope of this PR. - Relying on undocumented
zigsubcommands is a calculated risk, but given they are present in the source and necessary for the toolchain's functionality, it's a reasonable choice.
I have one suggestion to improve the changes. The toolkind rc is typically used for the Rust compiler. For the Windows Resource Compiler, xmake uses the mrc toolkind. I've added comments to suggest this change for better consistency and to avoid potential conflicts.
This patch fixes a dynamic linking problem when using autotools with zigcc.

This patch has been tested and works, but there are two questions🤔:
zig ld.lld(and other tools added in this patch) are not documented in the zig, but I think they just forgot to update the documentation.https://github.com/ziglang/zig/blob/a027fa8b8c03f8c325c4347500d0487c6d366f81/src/main.zig#L283
