ares_build.h.dist: enhance non-configure GCC ABI detection logic
GCC specific adjustments:
- check __ILP32__ before 32 and 64bit processor architectures in
order to detect ILP32 programming model on 64 bit processors
which, of course, also support LP64 programming model, when using
gcc 4.7 or newer.
- keep 32bit processor architecture checks in order to support gcc
versions older than 4.7 which don't define __ILP32__
- check __LP64__ for gcc 3.3 and newer, while keeping 64bit processor
architecture checks for older versions which don't define __LP64__
