Minor bug in Makefile.hal

Hi guys,
i’m building for CW308_STM32L4 and when i do make, evreything’s gone ok but i see a “Built for platform CW308T: STM32L5 Target” instead of “Built for platform CW308T: STM32L4 Target”. Bug detected in https://github.com/newaetech/chipwhisperer/blob/develop/hardware/victims/firmware/hal/Makefile.hal line 221. I didnt wanna open a pull req for this dumb stuff however I let u know.

Thanks for the heads up! This should be fixed now.
