glibc itself is not supposed to be linked statically, because it itself dlopens other shared libraries - for pam, for nsswitch, etc. These are system specific (as configured by admin), so there is no one size fits all. You may statically link another libc, but then the users may wonder why your app does not works as it should, when they configure nsswitch for example and your app will not respect that.
