Hello Guix!

I=E2=80=99ve just watched Mark=E2=80=99s very nice talk about debuginfod an=
d and I=E2=80=99d
like to work towards running an instance of it on ci.guix.gnu.org:

  https://fosdem.org/2020/schedule/event/debugging_debuginfod/

What=E2=80=99s missing today is configuring GCC with =E2=80=98--enable-link=
er-build-id=E2=80=99
(which is not the default, unlike what Mark says in the talk :-)).

If we do that, I wonder if we can stop using =E2=80=98.gnu_debuglink=E2=80=
=99 (see the
=E2=80=98strip=E2=80=99 phase in (guix build gnu-build-system)).

Also, I suspect build IDs wouldn=E2=80=99t mesh well with grafting: unless =
we
rewrite them, the same build ID would match both the ungrafted and the
grafted variant.  Is that a problem?  Not sure.  (Currently (guix build
debug-link) recomputes =E2=80=98.gnu_debuglink=E2=80=99 upon grafting so th=
at the links
remain valid.)

Thoughts?

Thanks,
Ludo=E2=80=99.

PS: I found Eelco Dolstra=E2=80=99s dwarffs to be very smart, too!
