... to reduce the number of simultaneously open files at link time. When plugin support is enabled in the linker, BFD's (and the corresponding file handles) are cached for the plugin to use. This results in quite a large number of simultaneously open files, which hits the default limit on macOS (256 files). Since we aren't using LTO now, disable it explicitly when invoking the linker.
