    x86: Don't remove empty GNU_PROPERTY_X86_UINT32_OR_AND properties

    For GNU_PROPERTY_X86_COMPAT_ISA_1_USED and GNU_PROPERTY_X86_UINT32_OR_AND
    properties, a bit in the output pr_data field is set if it is set in any
    relocatable input pr_data fields and this property is present in all
    relocatable input files.  A missing property implies that its bits have
    unknown values.  When all bits in the the output pr_data field are zero,
    this property should not be removed from output to indicate it has zero
    in all bits.
