arch/arm32v8m/cmake: Fix clang's error in specifying cfg and target

Browse source 
1. -target should be in front, otherwise clang will not be able to find the corresponding libgcc.a
2. When using clang++ compiler to link, you also need to specify the corresponding arch, otherwise ld.lld will report an error due to arch mismatch.
