Hello. A few months ago I made the experiment of building
the archive with the new "make --shuffle" feature from make 4.4.

See:

https://trofi.github.io/posts/238-new-make-shuffle-mode.html

for details.

Well, "yosys" was one of the packages which FTBFS for me.
It was version 0.23-6, and it failed in a different way.

But something tells me that this bug reported by Lucas
could easily be another Makefile bug.

So, instead of trying to reproduce the problem by building
the package in your machine, I suggest that you take the provided
build log, collate it with the current Makefiles, and try to
determine how could it happen at all.

For example, the build log says this:

I can't find file `verilog_flow.aux'.

The interesting question here would be:

Are you sure that the Makefiles are correctly written in
such a way that the verilog_flow.aux file is always created
before some other process tries to use it?

Thanks.
