* elf32-spu.h (struct spu_elf_params): Add non_ia_text.
	* elf32-spu.c (mark_overlay_section): Only include .text.ia.*
	sections in soft-icache lines unless non_ia_text.  Don't add
	rodata if doing so would exceed line size.
ld/
	* emultempl/spuelf.em (params): Init new field.
	(OPTION_SPU_NON_IA_TEXT): Define.
	(PARSE_AND_LIST_LONGOPTS, PARSE_AND_LIST_OPTIONS): Add --non-ia-text.
	(PARSE_AND_LIST_ARGS_CASES): Handle OPTION_SPU_NON_IA_TEXT.
