   2# Makefile.basic lists the most basic programs used during the build process.
   3# The programs listed herein are what are needed to do the basic stuff,
   4# such as fix file dependencies.
   5# This initial step is needed to avoid files to be recompiled
   6# when kernel configuration changes (which is what happens when
   7# .config is included by main Makefile.
