ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Mon Nov 28 08:55:31 2016 +0100| [29d2e03ed96d9f7b8cb2cc87dca0a63c2a6eff70] | committer: Diego Biurrun

configure: Simplify and fix avfoundation indev handling

Handle extralibs in the standard way, add missing pthreads dependency.
Also globally check for -fobj-arc with Objective-C compilers since
that option is useful for other Objective-C code as well.
