[mythtv] [PATCH] Endian Fixes

[Mino Taoyama]

Enclosed is a patch against a 12/30/04 cvs checkout that adds the audio 
fixes for big endian machines. Thanks Nigel! It replace the 
WORDS_BIGENDIAN define with automatic endian detections.


The endian detection replaces
#ifdef WORDS_BIGENDIAN with #if (BYTE_ORDER == BIG_ENDIAN) || 
(__BYTE_ORDER == __BIG_ENDIAN)
#ifndef WORDS_BIGENDIAN with #if (BYTE_ORDER != BIG_ENDIAN) && 
(__BYTE_ORDER == __BIG_ENDIAN)

I also remove the TARGET_ARCH_POWERPC section in settings.pro since it 
was only being used to set WORDS_BIGENDIAN. It is probably safe to keep 
it in place but it is no longer needed.

The audio fix now allows any combination of Frontends an Backends to 
work together.

I've compiled and tested this patch with:

MacOS X (10.3.7)
linux-x86 (FC2)
linux-powerpc (YDL 4.0)

This patch still allows a MacOS X compile without any changes to 
settings.pro.

The only change I need now for a linux-powerpc build is to remove the 
MMX and -march=pentiumpro from settings.pro.  (I'll see if I can make 
this automatic, but looking at the Qt docs it doesn't appear to provide 
an obvious way to do architecture detection.)
