config.gcc (arm*-*-symbianelf*): Add t-symbian Makefile fragment.

	* config.gcc (arm*-*-symbianelf*): Add t-symbian Makefile
	fragment.
	* config/arm/bpabi.h (RENAME_LIBRARY_SET): Fix typo.
	(SUBTARGET_EXTRA_ASM_SPEC): Pass -meabi=3 to the assembler.
	* config/arm/symbian.h (SUBTARGET_CPU_DEFAULT): Assume ARMV5
	architecture.
	(SUBTARGET_ASM_FLOAT_SPEC): Default to -mfpu=vfp for hard-float
	configurations.
	* config/arm/t-symbian: New file.
