It seems this might have broken buildworld:

In file included from netlink_netlink_snl.c:1:                                                     
/usr/obj/usr/src/amd64.amd64/tmp/usr/include/netlink/netlink_snl.h:244:25: error: cast from 'char *
' to 'struct nlmsghdr *' increases required alignment from 1 to 4 [-Werror,-Wcast-align]           
        struct nlmsghdr *hdr = (struct nlmsghdr *)&ss->buf[ss->off];                               
                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

I'm getting tons of errors like these with `make -sj10 buildworld`.
