I think the macro here is just a workaround for the fact that SYS32ONLY()
always prepends the name with 'compat_' for the compat version, and there
is no other macro to do this. After the conversion, this can easily be
done using the regular table, as you need separate names for the
32-bit entries anyway.

The spu_callbacks.c and systbl_chk.c files don't need this macro,
but that doesn't matter once you drop this patch.
