ARMClang: CMAKE_ASM_COMPILER_TARGET does not take effect when compiling Assembly ARM code
See issue #19962 (closed) for the same configuration. When compiling Assembly code with the same CMakeLists.txt, armclang does not get --target=CMAKE_ASM_COMPILER_TARGET such that it complains --target is not defined and stop compiling. With C code, --target option is appened as expected.
