The reason for 531# this is the following: 532# To know the configuration, the main Makefile has to include 533# .config. That's a obviously a problem when .config doesn't exist 534# yet, but that could be kludged around with only including it if it 535# exists. 536# However, the larger problem is: If you run make *config, make will 537# include the old .config, then execute your *config. It will then 538# notice that a piece it included (.config) did change and restart from 539# scratch. Which will cause execution of *config again. You get the 540# picture. 541# If we don't explicitly let the Makefile know that .config is changed 542# by *config (the old way), it won't reread .config after *config, 543# thus working with possibly stale values - we don't that either. 544# 545# So we divide things: This part here is for making *config targets, 546# and other targets which should work when no .config exists yet. 547# The
