The idea is to black list platforms that don't do %zu and there is no
way to do that without breaking cross-compilation. It is still
preferable to use that if it is available, e.g. to help format string
checks.

Doesn't work as the preprocessor doesn't know what sizeof(size_t) is.
The macros are pre-computed similar to what genassym is doing for the
NetBSD kernel build.
