    Fix internal error with -z relro when .tbss is last relro section.
    
    When calculating the padding necessary to align the end of the relro
    segment to a page boundary, gold erroneously ignores the .tdata section
    when checking to see if there are any relro sections (so if .tdata
    is the only relro section, we fail to align the segment properly),
    and erroneously pads the cumulative size of the segment based on
    the alignment of .tbss. If there are no relro sections following .tbss,
    it then fails to note the padding needed at the end of .tdata.
    
    This patch fixes both problems. is_first_section_relro() will return
    true when it sees a .tdata section, and we do not align the cumulative
    size until after checking for the .tbss section.
    
    gold/
    	PR gold/14217
    	* output.cc (Output_segment::is_first_section_relro): Don't ignore
    	.tdata section.
    	(Output_segment::set_section_addresses): Don't align size of relro
    	segment for .tbss.
