[PATCH] libnl: optionally disable cli tools.

[Karl Hiramoto]

compile and link time can reduced, most non-developers don't need these cli tools.

./configure --disable-cli
time make
real    0m40.485s
user    0m33.784s
sys     0m2.793s

./configure
time make
real    0m53.097s
user    0m42.077s
sys     0m4.396s
