cmake: fix native build on arm

uname -m on 32bit Arm platforms (little endian) report a machine string like armv5tejl, armv7l or armv8l. A native build on these machines fail: CMake Error at lib/processor/CMakeLists.txt:1 (add_subdirectory): add_subdirectory given source "armv8l" which is not an existing directory. Set PROJECT_PROCESSOR to arm on these machines. Signed-off-by: Benedikt Spranger <[email protected]>
