This broke the build on 15:

/usr/bin/strip /wrkdirs/usr/ports/cad/yosys/work/stage/usr/local/bin/*
/usr/bin/strip: error: '/wrkdirs/usr/ports/cad/yosys/work/stage/usr/local/bin/yosys-config': The file was not recognized as a valid object file
*** Error code 1

Please fix. And test better next time.
