having trouble building espruino for STM32F411DISCOVERY

In fact I had downloaded a zip. But today I tried the

git clone https://github.com/espruino/Espruino

method. And sort of good news, I got a different error.

[user@hostname Espruino]$ sudo STM32F411DISCOVERY=1 WIZNET=1 make
CC src/jslex.o

I see it knew to grab my /usr/lib/gcc/arm-none-eabi this time, so i assume it's not a path problem.
