* emultempl/pe.em (debug_section_p): New bfd_map_over_sections hook.
(gld_${EMULATION_NAME}_after_open): Use it to iterate all sections
of all input BFDs, looking for debug info. Enable long section names
if any found.
* emultempl/pe.em (debug_section_p): Likewise.
(gld_${EMULATION_NAME}_after_open): Likewise.
* NEWS: Retrospectively adjust news announcement.
* ld.texinfo: Update documentation to mention new behaviour.
