Looking at the output I found the following:

I dug into this a bit, and was able to get a pdb successfully made with the attached patch.

However, it doesn't address that other flags (CFLAGS/CXXFLAGS) are being sent to the linker and causing other unknown argument issues. I suspect this is because the static analysis plugin is the only HostSharedLibrary in the tree and not well supported.

Attachment: Bug 1576758 - Correct a HostSharedLibrary's link command to correctly output a pdb r?#build

-Fd is the parameter accepted by clang. -PDB is the parameter accepted by lld-link. Additionally, to produce a pdb you apparently also need the -DEBUG flag
