The assembler option -mauto-it is no longer a valid option. It has
been removed from the documentation in July 2009, which is well
before the release date of the currently supported binutils version
2.20.

Do you by chance have a link to the relevant commit?

Is $(comma) still needed? I thought it was only needed when a flag
that would contain commas would be in another set of parens (thus
making an ambiguity), like cc-ldoption or such?  Can you replace
`$(comma)` here with `,`?  I suspect it should work.

Documentation got removed in
https://github.com/bminor/binutils-gdb/commit/529707530657a333a304c651c808ea630c955223

I think -mauto-it never really made it upstream. Documentation has been
introduced here, but it seems that the option already has been renamed:

Could catch, yes comma should work here.

The minimum version of binutils as per
Documentation/process/changes.rst is 2.20. Looks like 2.20 was
released around 2009-09-04:

Cool, if you wouldn't mind sending a v2 with that change, feel free to
add my reviewed by tag.
