Compiling xen-unstable in 32bit chroot on amd64

Compiling xen-unstable in 32bit chroot on amd64

[Robin van Leeuwen]

I've got two computers here one amd64 3500/2GB/debian-amd64-testing
and a amd-duron-900/512mb/debian-testing.

I've setup a 32-bit chroot on my amd64 and want to
compile xen-unstable in the32 bit enviroment to
run xen on the duron. Because compiling after "make mproper"
on the Duron takes about 2 hours, and on the amd64 about 5
miniutes. I'm stuck on compiling in the 32 bit chroot:

The build system thinks you are targetting x86_64. There are two fixes: 
either run 'setarch i686', which will change the output of the uname 
command, or build Xen with 'make XEN_COMPILE_ARCH=x86_32'.

Thanks, the "make XEN_COMPILE_ARCH=x86_32" works, this saves me
about 5 hours of compiling time per day :-)
