[FFmpeg-devel] [PATCH 3/5] configure + lavc/Makefile: define build infrastructure for libaribcaption

[TADANO Tokumei <aimingoff@pc.nifty.jp>]

To compile with this feature:
* libaribcaption external library has to be pre-installed.
  https://github.com/xqq/libaribcaption
* configure with `--enable-libaribcaption` option.

`--enable-libaribb24` and `--enable-libaribcaption` options are
not exclusive. If both enabled, libaribcaption precedes as
order listed in `libavcodec/allcodecs.c`.
