- Do not use += to set initial CONFIGURE_ARGS value
- Convert to option helpers and new test framework (TEST_TARGET)
- Remove extra patch that prevented installation of the example files
(it is not needed in the post-staging era: running `make package
OPTIONS_UNSET=EXAMPLES -DBATCH' will produce package without the
exampes by default, requiring no special hacks)
- Wrap one overly long line by optimizing away one of the STRIP_CMD's
