having trouble building espruino for STM32F411DISCOVERY

I understand that once i fix the Command not found issue, make will sort itself out by taking instructions from the makefile

What method do you normally use to add a command to the path? In my limitted understanding, I managed to get the /etc/environment file to work for me before, but if there's a better way, please comment. I'm here again with a freshly installed Ubuntu 14.04 VM.

The build process was successful on Arch Linux without a VM. I installed the compiler in the following manner: yaourt arm-none-eabi-gcc49-linaro

The AUR package took about 30 minutes to build on a 4GHz Core i7
And Espruino took maybe 5 minute to build.

Now for the hardware step
