(assign_file_positions_for_non_load_sections): When setting up
PT_GNU_RELRO header, don't require a corresponding PT_LOAD
header that completely covers the relro region.

* ldlang.c (lang_size_sections): Remove unneeded RELRO base
adjust. Tidy comments.
* ld.texinfo (DATA_SEGMENT_RELRO_END): Correct description.
