Makefile: Warn if submodule status '+'-prefixed

Browse source 
A '+'-prefix means that the submodule is initialized and checked out, but a different commit is checked out.
If this is accidental then the user should run `git submodule update` to fix it.
If it is intentional (because e.g. the user is explicitly wanting to test Yosys with a different version of abc), then creating a new commit in Yosys to update the expected commit is also a valid solution.
