Description: The following line from package():
echo -e '/usr/lib/\n/usr/lib/ffmpeg2.8/' > "${pkgdir}"/etc/ld.so.conf.d/ffmpeg2.8.conf

creates an ld.so.conf.d configuration that specifies /usr/lib, such that any configuration file that follows alphabetically that intends to point to other directories as an override for libraries in /usr/lib will be negated by this instance of /usr/lib added to the search path order prior to it being automatically appended at the end.

For example, if there was a file /etc/ld.so.conf.d/foo.conf that contained "/usr/lib/foo" for foo.so as an override for /usr/lib/foo.so provided by some other package, this override would never be realized due to ffmpeg2.8.conf injecting /usr/lib in the search order before /usr/lib/foo.

/usr/lib never needs to be specified in these configuration files as it will be automatically added at the end.
