With NO_WRKSUBDIR set, there's no need for a roll-your-own extraction
target, so remove it from this port.
While here:
- use <options> instead of <pre> + <post> includes
- Wrap the compound commands in parentheses and use "&&" conjunctions
instead of ";" for better multijob support
- Remove several command masks (@) that were suppressing log output
- Remove duplicate (and broken) softlink creation in lib target
- Fix second (also broken) softlink creation in do-install target
- Revbump for last
- Fix WWW whitespace
- Remove redundant @dirrm
