[yosys] update to 34

[sjkelly]

This is a simple version bump, but the dependencies list is quite old at this point. Is there a good way to update the dependency compats automatically?

Is there a good way to update the dependency compats automatically?

No, also because I don't that's a well defined process

@sjkelly do you want to update the compats, or should we just merge this in and that be done later?

[sjkelly]

Since it builds, I suppose we can merge in the interim. I have been prototyping an update script to automate this.

Merge?
