Subject: Check for and use flags to reject undefined symbols in libraries.
X-Git-Tag: submit/2.0-panda/20130828.192557~1653
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a4703ce7e8be3be6dfa3511f5b4356720589754a;p=profile%2Fivi%2Fpulseaudio-panda.git

Check for and use flags to reject undefined symbols in libraries.

Make sure that all the PulseAudio modules are built properly without
outstanding undefined symbols: if the undefined symbols are found, reject
link.
