Provide option to avoid defining a custom version of uintptr_t.

There's a definition in stdint.h (provided by gcc) which will be more correct
if available.

Define CONFIG_USE_STDINT to use this feature, or USE_STDINT=1 on the 'make'
commmand.

This adjusts the settings for x86 and sandbox, with both have 64-bit options.
