Looks like the paths are wrong (VPATH is set to ..) and -I paths are referencing not valid paths.

I wasn't able to replicate this issue.

I was not able to reproduce this issue.

False alarm, my paths were corrupted thus arm-none-eabi-gcc was not found - I found once I was trying to use gcc in the command line (in the above was g++). Can we add a check if gcc/g++ is in present and fail prematurely in the Makefile?

From a performance perspective, this is not going to make any difference. This is actually a bit difficult, as there is no cross platform which/where and the errors returned on multiple platforms are very different.
