CoreFoundation not linked with 5.4 and dev snapshots

Even when not using LTO, I'm seeing these linker errors:

Current workaround is to pass all Foundation-related linker flags manually, as in

swift build --triple wasm32-unknown-wasi \
  -Xlinker -lCoreFoundation -Xlinker -licuuc \
  -Xlinker -licui18n -Xlinker -luuid -Xlinker -lBlocksRuntime
