[PATCH/AARCH64 1/6] Fix size and pointer different types for ILP32.

[Andrew Pinski]

While compiling some programs, GCC and glibc (and newlib)'s definitions of 
size_t
were not agreeing and causing format warnings to happen.  The simple testcase 
for this is:
#include <stdio.h>
#include <stdint.h>

int main(void)
{
  ssize_t t = 0x1;
  printf("%zd\n", t);
  return 0;
}
----- CUT -----

OK?  Built and tested for aarch64-elf without any regressions.

Thanks,
Andrew Pinski



        * config/aarch64/aarch64.h (SIZE_TYPE):  Set to unsigned int for ILP32.
        (PTRDIFF_TYPE): Set to int for ILP32.
