From the comment, I expect this code creates autoksyms.h in case it
is missing, but it actually touches it when it does exists.

I do not know when this code is useful...

If autoksyms.h were missing, build should have already failed because
include/{linux,asm-generic}/export.h need it.

Maybe for standalone test?
Or, in order to make this script self-contained?

Oops, indeed.

I agree it isn't very useful. Proof: it was wrong and wouldn't have 
worked as intended. So the best fix might be to simply remove that line.

OK, I will remove the code.
