And you have a known-elf.awk. elfutils really should steal that one.
(Or just completely adopt your dw-tools :)

We probably should just introduce real string functions. They are useful
on their own. I had a proposal for them some time ago. I'll find them
and post a proposal. And maybe we can add similar ones based on

I am not entirely against it. But I am somewhat hesitant because it is
hard to define what interface we really are exporting with them.
Currently they really are implementation details. And they are not
completely consistent. There are "bare" constant KNOWNs and others with
DESCriptions. Some even mix the two. So we should first decide which to
export and make them consistent (never or always include the description
string). And there is no documentation for them. There should at least
be a description of how to use them correctly.
