Revised the top-level Makefile so that it does not need to declare
targets for each technology but will enumerate the valid technologies
discovered at the time of doing "autoconf" and the enabled
technologies declared by "configure". Also modified the "find"
command in the configure script to search symbolic links. This allows
additional target technologies to be added to the directory without
needing to update the top-level Makefile (although "autoconf" will
have to be re-run), and it allows new technologies to be added by
symbolically linking to the directory. This is important for non-free
technologies that cannot be distributed with open_pdks.
