Use ULONG_MAX instead of __WORDSIZE to determine native ELF architecture

Browse source 
__WORDSIZE is an internal libc definition. Instead, we can use
ULONG_MAX from limits.h, whose value corresponds to the machine's
native word size.

This allows us to remove the fallback definition of __WORDSIZE in
the Android compatibility headers.
