[Voyage-linux] compile for voyage 0.4

[Paul Hays]

I've been running Voyage in a qemu virtual machine for this. The host 
system is Ubuntu. See
http://wiki.voyage.hk/dokuwiki/doku.php?id=voyage_in_qemu&s=qemu

The first time I started my Voyage image in qemu, I set the timezone, 
then configured Voyage so it will use qemu's built-in network support:
     remountrw
     tzconfig
     cd /etc
     sed -e s/^/#/ dnsmasq.more.conf >aaa
     mv aaa dnsmasq.more.conf
     shutdown -h now

This change let the Voyage system uses my LAN as if qemu were a NAT device.

Executing the following script on the host boots Voyage and enables ssh:
    # boot big_voyage image as client OS inside qemu emulator
    # -m dedicates 512M of RAM to the emulator
    # -redir lets us connect from host to client
    #    with "ssh -p 2222 root at 127.0.0.1"
    qemu -hda big_voyage.img  -nographic  -no-kqemu  \
        -m 512  -redir tcp:2222::22

(Ssh access is useful because qemu's emulated serial console drops many 
characters when displaying any big block of text.)

The time-of-day clock in Voyage is very inaccurate, causing difficulty 
with "make" and file timestamps. (The emulated CPU seems to drop many 
clock interrupts). I tried to solve that using NTP, but it seldom 
managed to synchronize the clock. As a partial fix, I added jobs to 
/etc/crontab in Voyage to set its software clock from the hardware clock 
twice a minute. On the host, I used "hwclock --systohc" to match the 
real hardware clock to the host's software clock. (I'd love to hear 
about a better solution that is actually in use!)

I edit my program source files on the host machine. They live in a 
directory tree that the host exports for access by nfs-over-ssl. The 
directory is mounted below /rw in Voyage, for convenient access by its 
compiler. See http://www.samag.com/documents/s=4072/sam0203d/sam0203d.htm.
