The reason for 572# this is the following: 573# To know the configuration, the main Makefile has to include 574# .config. That's a obviously a problem when .config doesn't exist 575# yet, but that could be kludged around with only including it if it 576# exists. 577# However, the larger problem is: If you run make *config, make will 578# include the old .config, then execute your *config. It will then 579# notice that a piece it included (.config) did change and restart from 580# scratch. Which will cause execution of *config again. You get the 581# picture. 582# If we don't explicitly let the Makefile know that .config is changed 583# by *config (the old way), it won't reread .config after *config, 584# thus working with possibly stale values - we don't that either. 585# 586# So we divide things: This part here is for making *config targets, 587# and other targets which should work when no .config exists yet. 588# The
