    xen/arch/x86: make objdump output user locale agnostic
    
    The objdump output is fed to grep, so make sure it doesn't change with
    different user locales and break the grep parsing.
    This problem was identified while updating xen in Debian and the fix is
    needed for generating reproducible builds in varying environments.
