This adds jq (1.5) which is a command line filter for processing JSON. Configure warns about missing Ruby dependencies which I'm ignoring since we don't have proper manpage support yet and I don't see a need for bringing in additional bloat when disk space is limited for us to begin with. Also, regex support requires oniguruma which will come shortly.

Tested sucessfully on Samsung Chromebook 3 (XE500C13-K01US).
