Normally that would use a target hook to specify the values of those
macros. The default would be the traditional Unix values of 0, 1, 2 for
O_RDONLY, O_WRONLY, O_RDWR, while Hurd would need its own definition of
the hook to use values 1, 2, 3 (I don't know if there are any non-Hurd
systems not using the traditional values).
