[PATCH] i386: Define __ILP32__ and _ILP32 for all 32-bit targets

[Gerald Pfeifer]

A user reported that gcc -m32 on x86-64 does not define __ILP32__ 
and I found the same on i686 (with gcc -x c -dM -E /dev/null).

The code has

      if (TARGET_X32)
        {
          cpp_define (parse_in, "_ILP32");
          cpp_define (parse_in, "__ILP32__");
        }

so -mx32 does define __ILP32__.  

This patch does the same for all "regular" 32-bit x86 targets.
Tested on i386-unknown-freebsd11.3 so far.

Okay?

Gerald


	* config/i386/i386-c.c (ix86_target_macros): Define _ILP32 and
	__ILP32__ for 32-bit targets.
