[arm] SymbianOS multilibs

[Paul Brook]

Now that I've fixed -mfloat-abi=softfp, the SymbianOS configuration needs to 
use this for its multilib.

Patch below makes this change.  It also makes SUBTARGET_ASM_FLOAT_SPEC pass 
-mfpu=vfp and -march=armv5t to the assembler unless told otherwise.

Tested by building an arm-none-symbianelf cross.
Ok?

	* symbian.h (SUBTARGET_ASM_FLOAT_SPEC): Default to -mfpu=vfp
	-march=armv5
