* emultempl/elf32.em (gld${EMULATION_NAME}_finish): Only emit this
function when LDEMUL_FINISH isn't set to the same name. Don't
call ${LDEMUL_FINISH}.
(ld_${EMULATION_NAME}_emulation): Call $LDEMUL_FINISH if defined.
* emultempl/armelf.em (arm_elf_finish): Call
gld${EMULATION_NAME}_finish.
* emultempl/hppaelf.em (hppaelf_finish): Rename to
gld${EMULATION_NAME}_finish. Call bfd_elf32_discard_info and
hppaelf_layout_sections_again if necessary.
(need_laying_out): New var.
(hppaelf_layaout_sections_again): Rename to
hppaelf_layout_sections_again. Clear need_laying_out.
(PARSE_AND_LIST_OPTIONS): Format text.
