Ok, so I was right in my gut(son)[1] feeling that -mauto-it was a
predecessor of -mimplicit-it -- and actually only in the first
iteration(s) of the patch that would have introduced it.

I've gone through the binutils git tree, and -mauto-it is mentioned
only in a patch that fixes the gas /docs/ which erroneously mentioned
-mauto-it where it should have mentioned -mimplicit-it.

Hence, I think we should not test for -mauto-it at all, and not
mention it even.

Stefan, can you resubmit without the -mauto-it part, and renaming
AFLAGS_AUTOIT into AFLAGS_IMPLICIT_IT?
