Due to legacy code, make pnr would print out an internal Makefile error at the end of the run. While this error was inconsequential and did not affect anything, it still needed to be removed.

sky130 18T and 15T cell libraries removed
...
Upon noticing their size, concerns were raised about available drive space.
As 12T is the main implementation focus, the decision was made to remove 15T and 18T.
Apologies if any were interested in implementing the processor across multiple standard cell libraries for comparison.
