// NaCl entry on 32-bit x86 has DI pointing at the arg block, which contains:
//
//	0(DI) - cleanup function pointer, always 0
//	4(DI) - envc
//	8(DI) - argc
//	12(DI) - argv, then 0, then envv, then 0, then auxv
// NaCl entry here is almost the same, except that there
// is no saved caller PC, so 0(FP) is -8(FP) and so on.
