Many errors while building open_pdk

[emfhasan]

I have run make command for building the open_pdk packages, but I came across the following errors for many unknown ef libraries and labels, can you advise:

@emfhasan Most (if not all) of these "errors" can be considered to be warnings, I believe. Did make open_pdks finish?

[RTimothyEdwards]

Yes, I have not done much clean-up of the open_pdks output, which runs a lot of different tasks and attempts to work around errors using different methods, but then dumps all of the error messages. As long as the "make" process finishes without raising an error itself and stopping early, then it has properly built the PDK.
