ngie 4fc7bbaf99 Expose the ILP32/LP64 programming environments based on
__ILP32__/__LP64__ instead of by architecture.

The list was incomplete (previous commits purged invalid architectures,
like __alpha__, but failed to add new ones). It's best to base the symbol
presence on whether or not the architecture is ILP32 / LP64 capable, per
the compiler.

This fixes the ILP32/LP64 program environments on some architectures like
arm64, and by proxy fixes the tests on those architectures.
