Can't build from 0.42 tarball

[spth]

Version

The 0.42 tarball (can't build, so can't give yosys --version otuput)

On which OS did this happen?

Linux

Reproduction Steps

tar -xzf yosys-yosys-0.42.tar.gz
cd yosys-yosys-0.42/
LANG=C make

Expected Behavior

yosys builds (like it does for me when using the 0.40 or 0.42 tarballs).

Actual Behavior

yosys fails to build, giving this erroer message:

Initialize the submodule: Run 'git submodule update --init' to set up 'abc' as a submodule.
make: *** [Makefile:748: check-git-abc] Error 1

Related to #4403 and the same as #4403 (comment) wherein downloading via the release tar the abc directory is empty and the yosys directory is not a git repository, which also means the git submodule update --init command does not work.
