   Log Message:
   Explicitly override iconv checks on SunOS, as GNU libiconv will change its
   own signature based on whether it finds itself already installed somewhere,
   which then breaks software (e.g. QT) which assumes its native signature.

   Restricted to SunOS for now as that's where it has been tested with positive
   results, but likely will be useful everywhere.

   Bump PKGREVISION.
