Created a custom script to add the line "USEMINSPACING OBS OFF" to
each of the standard cell technology LEF files. This is the correct
setting, as otherwise macros with obstruction areas won't be handled
correctly by place & route tools. Also: The custom script causes
the technology LEF file to flag as a mismatch in the "patch" file,
and "patch" creates a backup file with a ".orig" extension. So the
".orig" extension has been added to the list of file extensions to
ignore when doing "make install".
