The root cause is:

  1. When building SPRTL, arch type is fetched from GNUARM cmake file since SPRTL CMake file is included with add_subdirectory() instead of include().
  2. The CM0+ arch type should be "armv6s-m". However, it is set to "armv6-m" in GNUARM cmake file, which stands for CM0. CM0 doesn't support SVC. Thus the build failed.
  3. Previously, the psa_client.c and` psa_service.c` were not in SPRTL folder. When building the both files, cpu type is fetched which is correct.

Fix the arch type of CM0+ to "armv6s-m" in GNUARM cmake files.

Add an arch type string "ARMv6S-M" for Cortex-M0plus in GNUARM.
Because Armclang doesn't have a dedicated flag as "armv6s-m", twostrings "ARMv6-M" and "ARMv6S-M" exist and stand for Cortex-M0plus arch type in Armclang and GNUARM respectively.
