You'll still have a completely separate toolchain. First, a lot (most?) embedded development is not done on ARM A. ARM Cortex-M is probably the most popular embedded platform in industry and what it shares with "ARM Cortex-A" is the brand "ARM"; otherwise it is a separate architecture and instruction set. Even if you are talking about doing ARM Cortex-A series, you aren't going to be using the same libraries on the embedded device that you use on a Mac. You'd most likely be using either Linux (ala Raspberry Pi) or an RTOS; either way you have a different compiler and stdlib to use.
