* elf32-arm.c (elf_backend_default_use_rela_p): Define to zero for 

SymbianOS.

	* emulparams/armsymbian.sh (OTHER_READONLY_SECTIONS): Define, so
	as to include .ARM.exidx$${Base,Limit}.
	* ld/scripttempl/armbpabi.sc: Move .plt to end of text segment.
	Define IMAGE$$ER_RO$${Base,Limit} and SHT$$INIT_ARRAY$${Base,Limit}.
	Put .init_array, .fini_array, etc. into the read-only data
	segment.
