Fail to build on linux

[Domingo Alvarez Duarte]

Hello !
Following the instructions I get this output:

genie --file=genie/genie.lua --gcc=linux-gcc gmake
./MTuner/genie/genie.lua:14: attempt to call a nil value (global 'setPlatforms')
stack traceback:
	./MTuner/genie/genie.lua:14: in main chunk
	[C]: in upvalue 'builtin_dofile'
	[string "premake = { }..."]:109: in function 'dofile'
	[string "_WORKING_DIR        = os.getcwd()..."]:37: in function '_premake_main'

Cheers !
