Options to define platform:
(1) Run make with PLATFORM specified as follows:
make PLATFORM=PM3EASY

(2) Save a file called Makefile.platform with contents:
PLATFORM=PM3EASY

or if you have a Proxmark 3 RDV4 with the BT add-on:
PLATFORM=PM3RDV4
PLATFORM_EXTRAS=BTADDON

!! Make sure to "make clean" when you change platform settings !!
