[Vm-dev] I need help building Cog on 64bit Linux (new Squeak server)

I've been banging my head against building Cog on the primary new Squeak 
server off and on now for a couple of weeks.  This server is 64bit 
Debian.  Note that I don't need and am not trying to build a 64bit VM, a 
32bit VM is fine, at least for the time being.

I did of course read unixbuild/HowToBuild and the notes about building 
on 64bit.  Unfortunately that doesn't work, in fact it fails quite early 
during the configure step (details in a moment).  So after looking 
around a bit I decided that it was all wrong and instead '-m32' should 
be in CFLAGS.  Well that certainly got me a lot farther but then I run 
into issues linking where gcc is used but without CFLAGS and it goes all 
pear shaped.

So with my tail between my legs I go back today and try the original 
suggestion again and to see if I can fix/workaround it.  And in fact I'm 
doing that right now.  But then I also decided that I should ask for 
help, so here I am.
