It probably should be picked to the earlier glibcs as well, IIRC the
affected code was from 1997.  I'll try this and amend the patch.

Not sure about glibc/hurd, but I notice it does not have the other
security patches that 'glibc-2.23' has.  Picking those should be left to
someone able to easily test it IMO.

Side-note: I was really surprised that grafting glibc had become *this
easy*, but it seems to work in my testing.  I'll push this after
patching the older glibc variants unless there are further comments.
