    bhyve: Provide optional libfdt linking
    
    The arm64 port currently does not support ACPI, it instead builds up an
    FDT which is exported to the guest.  This mechanism will not be used on
    amd64 but isn't really arm64-specific either, so provide an opt-in
    mechanism to link libfdt.
    
    No functional change intended.
