[patch] Fix 32bit xen-tools build.

[kraxel@suse.de]

[-- Attachment #1: cross-build-fix.diff --]
[-- Type: text/plain, Size: 1379 bytes --]

This fixes building 32bit xen-tools on a amd64 machine, i.e.
"XEN_TARGET_ARCH=x86_32 make".

For ioemu I've taken the lazy path and just disabled them for
cross-builds, I'll leave that to fix to someone who knows the
qemu makefiles better than I do ;)
