[mythtv] Mythtv CVS on AMD64 wants -fPIC

[Rutger Hendriks]

Hi list,

the problem described below still applies on CVS for a few seconds ago
I have now -fPIC -DPIC -fPIC in the following variables:
CFLAGS, CXXFLAGS, LFLAGS, LIBS
in the Makefile in mythtv/libs/libavcodec

Any input is appreciated. I would really like to install the latest version 
because 0.16 keeps crashing on me :-(

Thank you,

Rutger Hendriks
