Xen devel - Aug 2012 - [TESTDAY] Compiling on 64-bit Ubuntu systems

It appears that we have a build dependency on 32-bit headers which
isn''t checked during ./configure, leading to strange-looking error:

Doing the following solved the problem (and Google was very helpful):

sudo apt-get install libc6-dev-i386

But it would be nice if the error message happen earlier and be a bit
more friendly.

I also added libc6-dev-i386 to debian package list at:

Can someone send a patch for the dependency list in the README too
please.
