I added -c back. Tried this and it works the same as without
-emit-interface-stubs
```
$ build/bin/clang -c -o - -emit-interface-stubs
clang/test/InterfaceStubs/weak.cpp clang/test/InterfaceStubs/virtual.cpp
clang-10: error: cannot specify -o when generating multiple output files
$ build/bin/clang -c -o - clang/test/InterfaceStubs/weak.cpp
clang/test/InterfaceStubs/virtual.cpp
clang-10: error: cannot specify -o when generating multiple output files
```
