    x86: enable long section names for xen.efi
    
    While for our present .data.read_mostly it may be deemed tolerable that
    the name is truncated to .data.re, for the planned .init.trampoline an
    abbreviation to .init.tr would end up pretty meaningless. Engage the
    long section names extension that GNU ld has had support for already in
    2.22 (which we consider the baseline release for xen.efi building).
