[Testsuite] – More fixes for remote execution: check_gc_sections_available, …

	* gcc.target/arm/multilib.exp (multilib_config): Pass flags to
	…_target_compile as (additional_flags=) option and not as source
	filename to make it work with remote execution.
	* lib/target-supports.exp (check_runtime, check_gc_sections_available,
	check_effective_target_gas, check_effective_target_gld): Likewise.
