I don't recall if I used debuginfod, but anyway I would need DEBUGINFOD_URLS to
point to the right server, I have no idea which server has the debug info for
these specific artifacts.

I don't really know how to do that since I never needed to.

I guess the best way would be to collect the required libraries (like you did),
but preserving the filesystem structure of the machine (e.g. have the libraries
as <root>/usr/lib/*.so).  And then use the "set sysroot" command.  I don't know
if there exists a tool that does this automatically, given a core dump, that
would sound useful.
