      kbuild: change out-of-tree build · 9e414032
      Masahiro Yamada authored
      This commit changes the working directory
      where the build process occurs.
      
      Before this commit, build process occurred under the source
      tree for both in-tree and out-of-tree build.
      
      That's why we needed to add $(obj) prefix to all generated
      files in makefiles like follows:
        $(obj)u-boot.bin:  $(obj)u-boot
      
      Here, $(obj) is empty for in-tree build, whereas it points
      to the output directory for out-of-tree build.
      
      And our old build system changes the current working directory
      with "make -C <sub-dir>" syntax when descending into the
      sub-directories.
      
      On the other hand, Kbuild uses a different idea
      to handle out-of-tree build and directory descending.
      
      The build process of Kbuild always occurs under the output tree.
      When "O=dir/to/store/output/files" is given, the build system
      changes the current working directory to that directory and
      restarts the make.
      
      Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
      syntax for descending into sub-directories.
      (We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
      This means the current working directory is always the top
      of the output directory.
