[mythtv] PATCH for AMD64

[Kyle Rose]

libavcodec wouldn't compile with gcc-3.4 without the following patch,
because apparently AMD64 cares about -fPIC, unlike IA32.  I have no
idea if the thing actually runs: I won't know until I get home
tonight.  I also didn't even try compiling with gcc-3.3.

Cheers,
Kyle
