[PATCH v2 13/14] add predefined macros for [u]int32_t

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

These are a pain. All LP64 archs use [u]int. Good.
But some LP32 archs use [u]int and some others use [u]long.
Some even use [u]int for some ABI and [u]loing for some others
(bare metal).

This really need to be target-specific to be correct.
