From a7f17b57a94e9cde6d7fa96ac86be5c4fc4f9211 Mon Sep 17 00:00:00 2001
From: Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>

Subject: [PATCH] valgrind: fix default debuginfo path
Description: Workaround for missing symbol in Guix's ld.so. The
correct fix (not stripping all the ld.so symbols) will be done in the
next Guix release as it requires to recompile a lot of packages.
Forwarded: not-needed
