    xen/elfnote: Specify ELF Notes are x86-specific
    
    The Xen ELF Notes are only used with x86.  libelf's elf_xen_note_check()
    exits early for ARM binaries with "ELF: Not bothering with notes on
    ARM".
    
    Add a comment to the top of elfnote.h specifying that Notes are only used
    with x86 binaries.  This is to avoid adding disclaimers for individual
    notes.
