[Question] Is `mold` any compatible at all with wine-tkg (and anything Wine related) to build? about mold

You can probably compile the Unix-side pieces with mold. Don't know if it's tested, but if it doesn't work already, it's probably not missing anything big.

You can not compile the DLLs with mold. mold can only emit ELF files, not PE.

The most problematic flags used by Wine is -Ttext and other executable-layout controlling flags for the preloader (which reserves certain address regions that are always reserved on Win32).

Wine generally have very low linking overhead as it's split into hundreds of DLLs with a small number of object files each. If you really wanted a more modern linker then LLD is officially supported (all you need is to set the native and cross compiler to clang). I'd suggest not messing with mold as it can create subtle issues that are hard to debug and not tested at all by upstream Wine developers.
