In-tree yosys binary doesn't have synth_{ecp,ice40} commands available #188

Need at least an alwayslink=True on the kernel link target and pointing somewhere else as the YOSYS_DATDIR in the defines. Been using out-of-tree binaries thus far, but we should be able to resolve this!

I think I've run into this issue before. I have a PR https://github.com/YosysHQ/yosys/pull/2417 out for it in yosys to allow you to set the datdir at runtime. Would that help?

You can also hack it together with something like this 

-DYOSYS_DATDIR='std::getenv(\"YOSYS_DATDIR\") ? std::getenv(\"YOSYS_DATDIR\") : \"{YOUR_DEFAULT_DATDIR_HERE}\"'
