Corrected a reference in the Makefile to "openlane" in the
Avalon Semiconductor library, which has been changed to
"librelane".  That removes a build Make error that appears to
have no consequence but was bothersome.  There is still an
issue where because the Avalon Semiconductor library does
not define any "maglef" files, the build process somehow
drops a "maglef" directory into libs.ref.  This is
innocuous and I will punt until later on solving it.
