Since GNU Mach commit d30481122a5d24ad6b921062f93b9172ef922fc3,
i386/machine_types.defs defines types based on defined(__x86_64__).
Supressing the built-in macro definitions will now result in the wrong
type being silently selected.
-undef was initially introduced in commit
78b6a7665db7b2eae367e17102821cbdca231d19 without much of an explanation.
-ansi was introduced in commit 6940fb91859e46b2e96a331a029f2dc2a0ee51c9
"to avoid -Di386=1 and the like".
Since glibc has been using MIG with CPP set to a custom GCC invocation
which did *not* use either flag, it appears that everything works well
enough even without them. On the other hand, not having __x86_64__
defined most definetely causes issues for anything that does not set a
custom CPP when invoking MIG (i.e., most users). Other built-in
definitions could be used in the future in a similar way (e.g. on other
architectures); it's really more of a coincidence that they have not
been used until now, and things kept working with -undef.
