Favor NotCompilation over CannotCache("multiple input files")

When the compiler is invoked for linkage, the command line usually comes
with multiple input arguments. It's confusing that sccache tells that
something is not cached because of the number of input arguments when it
wouldn't cache anyways because it's not a compilation in the first
place.
