    x86emul: inherit HOSTCC when building 32-bit harness on 64-bit host
    
    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.
