+#
+# This is the equivalent of https://github.com/docker/containerd-packaging/pull/390
+# for containerd packages, but unlike for containerd packages, we currently do
+# not run into this issue when building docker-ce packages. We're installing
+# this as a precaution, but perhaps it's not needed.
+#
+# go1.21 and up have a patch that enforces the use of ld.gold to work around
+# a bug in GNU binutils. See;
+# - https://github.com/golang/go/issues/22040.
+# - https://github.com/golang/go/commit/cd77738198ffe0c4a1db58352c89f9b2d2a4e85e
+#
+# Fedora 41 and up has a fixed version of binutils, and no longer requires that
+# patch, but may fail without ld.gold installed;
