[MacOS] Make qemu target failed on MacOS

[qiaojingx]

Description

Building qemu target on Mac failed after zephyr updated.

Test Code

All samples and tests

Steps to Reproduction

1. Building qemu on MAC by follow instructions: building-qemu-and-arduino-101-targets

Actual Result

1. Building qemu target failed on Mac, it needs i586-zephyr-elfiamcu not i586-pc-elf.
   I have no idea how to build i586-zephyr-elfiamcu via ct-ng build.

2. Try to change i586-zephyr-elfiamcu to i586-pc-elf in deps/zephyr/cmake/toolchain-xtools.cmake, another error met:

Expected Result

Building successfully.

@qiaojingx I've updated the mac instructions for qemu, see #1780, can you try to see if you can get it to build following them? I've ran into many issues on my mac running Sierra, so if you are using a different OS like High Sierra, you may or may not run into the same issues, I've tried to document the work-arounds I did and I am planning to file a bug on Zephyr, you can comment on the patch too if you see any issues so I can update it accordingly.

Verified with new instructions(#1780) for qemu, I can build qemu target successfully.

For arduino 101 target, and i met the below issue by following new instructions. Do you have any work-around for this?

@xiaoyu3x No I don't, did you build with iamcu.config instead of i586.config? Basically, we are just following the instruction here http://docs.zephyrproject.org/getting_started/installation_mac.html, if we can't build native Zephyr apps for A101 with the instructions, we need to file bug on Zephyr so they can fix it.

[jimmy-huang]

It turns out that the error you are seeing is because it's compiling the arduino_101 with the ARC compiler, not with the crosstool-ng one, since our Makefile builds both ARC and x86 at the same time. But I tried building just x86 by unsetting the CROSS_TOOL, then I am getting linker error with gcc, i think it should used clang instead of gcc. So I filed a bug
zephyrproject-rtos/zephyr#5807, hopefully they fix this, then we can probably update our Makefile to build it correctly.

[qiaojingx]

Thanks for trying this out. Can you add the issue (zephyrproject-rtos/zephyr#5807) to arduino 101 building in new instructions(#1780). Then we can close #1715 & #1714 after #1780 merged.

[jimmy-huang]

Yeah, I updated my PR to add the zephyr issue.

[qiaojingx]

Verified with commit 0c0af9b. Qemu target can be built by following new instructions. Close
