Due to lack of an ARM device, it is not certain if the same error happens when build through "Build and Run"

Repro:
1. Create an new or use an existing project
2. Build for UWP platform, and set Build Settings to Architecture = ARM, Build Type = Executable Only
3. Build

Actual: Error messages in the Console window and build fails in the Editor

Note: It seems this is caused by error in command line (ARM instead of ARMv7). See attached file for full error message
