Makefile: Test yosys git status in check-git-abc

Browse source 
As in #4986, `check-git-abc` is misleading if Yosys itself isn't a git repository.
So check `git status` before suggesting `git` based solutions, providing alternative suggestions for using ABCEXTERNAL (which bypasses `check-git-abc`), or downloading release tar (noting that the 'Source code' archives won't work, which is probably how they ended up in this situtation).
