Subject: [PATCH] make regex and asciidoc work on Darwin without hacking

- use $(PREFIX) when accessing files in /etc/asciidoc/...
  on Darwin, we use /sw
- remove obsolete reference to internal regex library
- configure script makes sure the BSD library isn't used on Darwin due to
  incompatibility
- document dependency on asciidoc
