helixhorned 68e6141c32 Patch adding Wii support by tueidj, part 10: sound and endianness changes 
This part is a mixture of the original patch and my changes.  It seems like
tueidj had some trouble
 1) getting OGG to work, which is why it's conditionally compiled out
 2) struggling with endianness with the mixing routines?  This may be also
    due to him missing to define two others BIGENDIAN macros (our code is
    in need of cleanup there).  Note the change in jaudiolib/src/mix.c!

Because I added my share to this part, I might have actually broken sound
mixing on big-endian platforms.
