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.

Rewritten to be an option, since stdint.h is often available only in glibc.
Changed to preserve a clear boundary between stdint and non-stdint
