Error make AT32

[AnOrdinaryUsser]

Hello everyone,

I saw that the repository could be useful to flash my hoverboard with AT32 processor and I want to see if I am able to get it.
However, I am having a little trouble, I have installed everything needed to do the make AT32, but I get this error from the terminal.
Can anyone tell me what is going on?
