libft timeout on to many extra functions

[Seluj78]

Add something like so :

if EXTRA_FUNC_COUNT > 10
then set MAKE_TIMEOUT = 60 seconds

for me, i had more than 15 extra functions , and no time out. not sure the issue is really the number of extra functions

@Seluj78 This is not a reliable test, as I commented on #65

Aright then we need to find a solution
