From 90d3edf01630093142e833235abea548aa78e65b Mon Sep 17 00:00:00 2001 From: Michael Forney Date: Mon, 14 Jun 2021 14:05:39 +0100 Subject: GNU gettext introduced this change[0] in version 0.19.8 to fix gettext detection with musl libc, since it does not define these internal symbols. This allows binutils to build with musl gettext rather than falling back to the bundled version.
