define HELP_DEFINITIONS
Options to define platform, platform extras and/or standalone mode:
(1) Run make with PLATFORM, PLATFORM_EXTRAS and/or STANDALONE as follows:
make PLATFORM=PM3EASY STANDALONE=$(HELP_EXAMPLE_STANDALONE)

(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

Default standalone mode is $(DEFAULT_STANDALONE).
To disable standalone modes, set explicitly an empty STANDALONE:
STANDALONE=
