I do not understand why #ifndef CONFIG_64BIT does not work...

...but #ifdef CONFIG_X86_32 works.

The latter is probably more correct, but really, under what circumstances would
CONFIG_64BIT=y hold when CONFIG_X86_32=y? Indeed the attached kernel config
does *not* have CONFIG_64BIT=y.

Something is wrong with the test results.
