add compiled features into --version output (#462)

a lot of application which allow selecting features at build time seem
to output the build config with `--version` or similar (e.g ffmpeg).

aside from giving the user information about the feature set the binary
was compiled with (in case the user didn't compile it themselves, e.g on
a binary distro) it can also (possibly) help when submitting bug
reports.
