From c5d033a34d0050dad83567eccd36dc6c7827ffe3 Mon Sep 17 00:00:00 2001 From: Sven Wegener Date: Mon, 28 Dec 2020 13:37:27 +0100 Subject: tools/fakeroot: remove undefined symbol messages glibc started to return errors from dlerror() for dlsym() lookup failures which results in a lot of messages from fakeroot like dlsym(acl_get_fd): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_get_fd dlsym(acl_get_file): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_get_file dlsym(acl_set_fd): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_set_fd when building OpenWrt using a recent glibc. Use the patch from the upstream Debian package to silence these messages.
