symbian.h (CC1_SPEC): Avoid passing duplicate options to the compiler.

	* config/arm/symbian.h (CC1_SPEC): Avoid passing duplicate options
	to the compiler.  Use -fshort-wchar by default.

	* gcc.dg/symbian4.c: Expect a 2-byte wchar_t, not a 4-byte
	wchar_t.
	* gcc.dg/symbian5.c: Test -fno-short-wchar.
