Address more linker issues

This resolves a ninja-related issues, corrects passing private args to linker
while building libruby itself (without external LDFLAGS), exports the full
symbols table, and pet 'pkg check -d'. Issues with weechat, vim, facter,
rubygem-hpricot and rubygem-rdiscount should be fixed.  See [1] for long story
of hunting and fixing these issues.

Bump PORTREVISIONS accordingly.
