Hi Joseph!

Then I guess we must undeprecate it.  I'm fine with that, as long as the
maintainers of ld(1) agree.  Joachim, would you mind sending a patch,
and CC binutils?  I'll leave it a week or two to gather reviews, and if
nobody opposes, I'll merge it.  I can also prepare the patch, if you
prefer.

Have a lovely day!
Alex
