Okay, apparently coff2yaml and yaml2coff are not in a great place as they
both don't deal well with the fact that you can have overlapping sections,
which seems to be what clang-cl produces (the .data section points to the
same place as a later section). Which is not a big big problem for me
particularly because msvc doesn't even generate .data sections in .obj.

I'm trying to put support for .bss sections in both coff2yaml and
yaml2coff... but I still can link just fine with my transformations
clang-cl generated files... what does give me problems is msvc .obj files.
Have you tried to link one of these?
