PR25243, static linking with exceptions and iostream is broken on ARM


	PR 25243
	* emulparams/armelf.sh (OTHER_READONLY_SECTIONS): Move definition
	of __exidx_start and __exidx_end into ARM.exidx.
	* emulparams/armelf_linux_eabi.sh (OTHER_READONLY_SECTIONS): Likewise.
	* emulparams/armsymbian.sh (OTHER_READONLY_SECTIONS): Similarly.
	* emulparams/elf32_tic6x_le.sh (OTHER_READONLY_SECTIONS): Similarly.
	* emulparams/armelf_fuchsia.sh: Source armelf_linux_eabi.sh,
	just redefining TEXT_START_ADDR.
	* emulparams/armelf_linux_fdpiceabi.sh: Source armelf_linux_eabi.sh,
	adding to OTHER_READONLY_SECTIONS.
