I realise this is a break from before and wants fixing on those grounds.

However, it is also wrong for OSSTest to be attempting to build a 32bit
hypervisor on any branch since 4.3.  It seems to me that there is a bug
there as well.

Independently of not falling over a missing defconfig, the following code

ifneq ($(XEN_TARGET_ARCH),x86_32)
        $(MAKE) -f Rules.mk _$@
else
        echo "*** Xen x86/32 target no longer supported!"
endif

Really needs to have an hard failure in it.  In fact, that is probably
the correct fix in this circumstance.
