Apply commit f6c8fecc6fe3d5532691867a7f27820bb1c426a9 from upstream
(still under GPLv2 at that time): Author: H.J. Lu <hjl@lucon.org> Date: Wed Sep 27 04:18:16 2006 +0000 PR ld/3223 PR ld/3267 * bfd/elf.c (assign_file_positions_for_non_load_sections): Don't warn zero size allocated sections. * ld/ldlang.h (lang_output_section_statement_type): Add section_relative_symbol. * ld/ldlang.c (strip_excluded_output_sections): Don't strip a section with a symbol relative to it. (lang_size_sections_1): Mark if an output section has a symbol symbol relative to it. This prevents warnings like the following during stripping of debug info from kernel modules on i386: ===> zlib (all) ... objcopy --only-keep-debug zlib.ko.debug zlib.ko.symbols objcopy --strip-debug --add-gnu-debuglink=zlib.ko.symbols zlib.ko.debug zlib.ko BFD: zlib.ko: warning: allocated section `.plt' not in segment BFD: zlib.ko: warning: allocated section `.got' not in segment
