When building ipvsadm this allows make to add to CFLAGS supplied
on the command line.

This seems to make sense as Makefile and libipvs/Makefile
add different CFLAGS but it may be desirable to supply supplementary
flags when building ipvsadm.

In particular the following may be useful when building ipvsadm
on Debian Jessie.

make CFLAGS='-I/usr/include/libnl3' LIBS='-lnl-3 -lnl-genl-3 -lnl-3 -lpopt'

For libnl3, what about ...

cflags: $(shell pkg-config --cflags libnl-3.0) $(shell pkg-config --cflags 
libnl-3.0)
libs:   $(shell pkg-config --libs libnl-3.0) $(shell pkg-config --libs 
libnl-genl-3.0)
