[OpenDivX] Small patch for OpenDivX

[Lionel Ulmer <lionel.ulmer@free.fr>]

Hi all,

As I am building OpenDivX on a non-X86 platform on Linux, I decided to
change a bit the Makefile in the Linux build section to support that. I also
used the new multi-platform capabilities to remove the 'bswapl' asm inline
code in the case of non-X86 platform.

I also wanted to remove the pow / log / ceil functions (it is VERY slow on a
non-FPU box), but it seems that somebody already beat me to it :-) So I just
removed the extraneous '#include <math.h>' files.

Feel free to comment and apply if it is correct :-)

        Lionel (honing his StrongARM ASM skills :-) )
