ld: Rewrite lang_size_relro_segment_1
1. Compute the desired PT_GNU_RELRO segment base and find the maximum
section alignment of sections starting from the PT_GNU_RELRO segment.
2. Find the first preceding load section.
3. Don't add the 1-page gap between the first preceding load section and
the relro segment if the maximum page size >= the maximum section
alignment. Align the PT_GNU_RELRO segment first. Subtract the maximum
page size if therer is still a 1-page gap.
