make for Banglejs problem with bootloader

I know it's pain to change, but are you ok with me adding this to the end of Makefile:

wrappersources:
	$(info WRAPPERSOURCES=$(WRAPPERSOURCES))

and then you can do make wrappersources instead of NO_COMPILE=1 make? Should be the same, but it just seems like it'd be a bit tidier and easier to maintain.

Ahh, interesting that tensorflow isn't relative! Yes, I recently changed to relative paths because when assertions were built into binaries they used to contain the entire path previously - which didn't seem great and also wasted a bunch of space
