Hmm.. this one is actually related to the libtraceevent. It seems glibc (and libdl) emits warnings if a static build try to link to the libdl functions (for obvious reason) and/or nss functions (which might use libdl). I found this article [1] but couldn't find how can suppress them. But as it's for loading plugins at runtime, we can disable the plugin support for static builds if we really nervous about the warnings.
