The kernel headers installed by Linux 2.6.19-rc1 "make
headers_install" do not work for building glibc, because glibc expects
<linux/rtnetlink.h> to provide various definitions, some of which have
been moved to <linux/if_addr.h> and some of which have been removed
altogether.
This kernel patch allows glibc to build again by making rtnetlink.h
include if_addr.h and adding back the removed definitions required by
glibc, but I don't know if it's the correct approach or if glibc
should change the headers it includes and add its own macro
definitions.
