 Summary of the bug: ffmpeg-0.10.3 fails to build on x32 ABI
 How to reproduce:

 Line 116 from libavfilter/libmpcodecs/vf_ilpack.c:

 #if HAVE_EBX_AVAILABLE
 static void pack_li_0_MMX(unsigned char *dst, unsigned char *y,
     unsigned char *u, unsigned char *v, int w, int us, int vs)
 {
     __asm__ volatile (""
         "push %%"REG_BP" \n\t"

 REG_BP defined in ./libavutil/x86_cpu.h:

 #if ARCH_X86_64
 ...
 #    define REG_SP "rsp"
 #    define REG_BP "rbp"
 ...
 #elif ARCH_X86_32
 ...
 #    define REG_SP "esp"
 #    define REG_BP "ebp"
 ...
 #else
 typedef int x86_reg;

 The question is: is it hard to provide support for the new x32 ABI which
 is now supported in kernel 3.4.x, glibc-2.16, gcc-4.7.1, binutils-2.22?
