[Xen-devel] Re: [PATCH] ioemu breaks build

[Anthony Liguori <aliguori@xxxxxxxxxx>]

Just a little more info.

The root cause of the problem is that HOST_ARCH is being set to `uname -i`.

On fedora, this produces "i386".  On Gentoo, this produces vendor_id 
from /proc/cpuinfo.
A better fix may be to set HOST_ARCH to i386 explicitly.  Since ioemu 
doesn't build for x86_32 this seems reasonable.
