Build PlatformStandaloneMmRpmb for ARM architecture (32bit arm machine).
The generated image targets an execution environment similar to AArch64 StMM secure partition in OP-TEE but in 32bit mode. GCC flag -fno-stack-protector added. The stack protection code bring GOT dependencies we prefer avoid when StMM runs in OP-TEE.
