* ldgram.y (DATA_SEGMENT_RELRO_END): Add one argument.
* scripttempl/elf.sc (DATA_SEGMENT_RELRO_END): Add 0 as first
argument.
(DATA_SEGMENT_RELRO_GOTPLT_END): Pass $SEPARATE_GOTPLT as first
and . as second argument.
(GOTPLT): Move $DATA_SEGMENT_RELRO_GOTPLT_END before the section.
* ldexp.c (fold_unary): Remove DATA_SEGMENT_RELRO_END handling here.
(fold_binary): Add it here. Insert padding to make relro_end
COMMONPAGESIZE bytes aligned. For DATA_SEGMENT_ALIGN in
exp_dataseg_relro_adjust phase just use previously computed
exp_data_seg.base.
* ldlang.c (lang_size_sections): Set exp_data_seg.base for
relro_adjust here. Call lang_size_sections_1 once more if there
was too big padding at DATA_SEGMENT_RELRO_END.
* ld.texinfo (DATA_SEGMENT_RELRO_END): Add documentation.
