Yes, I already have good reason to suspect this patch
2008-10-22 Alan Modra
* ldlang.c (lang_output_section_find_by_flags): Handle non-alloc
sections.
* emultempl/elf32.em (enum orphan_save_index): Add orphan_nonalloc.
(hold): Likewise.
(gld${EMULATION_NAME}_place_orphan): Handle non-alloc orphans.
causes the change in linker behaviour. Did you try the patch I posted?
