+Subject: [PATCH] libnm-systemd-core: Disable sd_dhcp6_client_set_duid_uuid
+ function
+
+When building on musl systems ( with out systemd ), and using LLD linker
+from LLVM project we fail to link with undefined symbols.
+
+This symbol is in sd_id128.c but its disabled, so let disable the functions
+which need this function.
+
