Remove --with-tuning

With the wide range of deployed 686 processors, -mtune=generic is saner
and it is the default anyway. The VLC defaults did not even make sense
anymore (Pentium 2, seriously?).

You might need to set -march explicitly as with other build systems,
e.g.: -march=i686

Changes between 2.0.x and 2.1.0-git:
--------------------------------
Important changes for packagers:
* The --with-tuning and --without-tuning options are removed. To tune
compilation for a specific processor type, set CFLAGS manually.
3rd party libraries (contrib):
* /extras/contrib has been replaced by a better system in /contrib
