Subject: [PATCH] [CMake] Add lib to swift host libraries link directories

Our libraries have a `LC_LINKER_OPTION` for eg. `-lswiftLLVMJSON`.
This is resolved (probably just based on the actual libswiftLLVMJSON.a
added to the link command) by ld, but not by lld. Add in a link
directory so that these libraries can be found.
