We're deliberately bringing XEN_COMPILE_ARCH and XEN_TARGET_ARCH out of sync in this case, and hence HOSTCC won't get set from CC. Therefore without this addition HOSTCC would not match a possible make command line override of CC, but default to "gcc", likely causing the build to fail for test_x86_emulator.c on systems with too old a gcc.
