> none-eabi targets
>
> c-c++-common/attr-simd-3.c fails to compile on arm-none-eabi targets
> due to -fcilkplus needing -pthread which is not available for those targets.
> This patch solves this issue by adding a condition to the cilkplus effective
> target that compiling with -fcilkplus succeeds and requires cilkplus as an
> effective target for attr-simd-3.c testcase.
