Beginning with version 1.5.1 openjpeg defaults to install its headers to
/usr/include/openjpeg-${major}.${minor} instead of /usr/include without
providing a compatibility symlink making the old test fail.

Done to keep ABI compatible. Otherwise this is just silly

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
