The reason these copies exist is because libnl frequently receives
support for recent new kernel features and the glibc headers take
a while to be updated. Some of the copies can probably be removed at
this point but it is difficult to figure out which as it might break
builds that are currently functionality.

Can you provide the compile error/warning? I thought we fixed the if.h
conflict.
