Olaf Seibert 2ac5184ff2 Add a configure script and remove a tangle of frail #if conditions 
This only uses autoconf, not automake or libtool or intltool or whatever.
This also allows easy building of different emulators in different build directories.

I have tested TOPS-20 with pcap|tap+bridge, ITS with pcap|tun|tap+bridge, both on NetBSD and Linux
and hopefully everything still works after the fine-tuning.
