-Subject: [PATCH] PR22829, objcopy/strip removes PT_GNU_RELRO from lld binaries
-
-lld lays out the relro segment differently to GNU ld, not bothering to
-include the first few bytes of .got.plt and padding out to a page at
-the end of the segment.  This patch teaches binutils to recognize the
-different (and somewhat inferior) layout as valid.
-
-bfd/
-	PR 22829
-	* elf.c (assign_file_positions_for_non_load_sections): Rewrite
-	PT_GNU_RELRO setup.
-ld/
-	* testsuite/ld-x86-64/pr14207.d: Adjust relro p_filesz.
