Crosscompiling iproute2

Hi,

i want to crosscompile (a modified version of) iproute2 (git://git.kernel.org/pub/scm/network/iproute2/iproute2.git) for armhf

do you any idea how?
configure-script seems to ignore "--host=arm-linux-gnueabihf" like i'm using for nftables

i modified Makefile

-CC := gcc
+CC := arm-linux-gnueabihf-gcc

-SUBDIRS=lib ip tc bridge misc netem genl tipc devlink rdma dcb man vdpa
+#SUBDIRS=lib ip tc bridge misc netem genl tipc devlink rdma dcb man vdpa
+SUBDIRS=ip

and run make like this to use static linking:

make LDFLAGS=-static

but it seems ip always needs libutil

make[1]: *** No rule to make target '../lib/libutil.a', needed by 'ip'.  Stop.

if i include lib in SUBDIRS i get many errors about missing libs like selinux and mnl

regards Frank
