Commit f797a96b authored by David Johnson's avatar David Johnson

Add support for Arch Linux.

This is pretty minimal "support", but it is working.  I have some
uncommitted fixes for event/linktest/iperf, however, as mentioned in
issue #351.

# before resolvconf runs for the first time on boot), res_init will
# return localhost, and there is no way for us in tmcc to know that is
