Modified the configuration file to better handle the installation
options. In particular, removed the "install-local" and "install-dist"
targets in favor of just using "make install", with the install type
dependent on the choices made by "configure". Made the local and
distributed install paths specific to the PDK. Added the link type
and efabless-style to the configuration options. Added a list of
generic standard cell gates to be used by (not yet posted) software
to automatically generate digital symbol libraries.
