Linux Headers question

[Reece Dunn]

Hi,

In the sections on building the Linux headers from the kernel sources,
the build instructions are (for section 6):

    make mrproper
    make headers_check
    make INSTALL_HDR_PATH=dest headers_install
    cp -rv dest/include/* /usr/include

What is the rationale behind the last two lines? Why not simply run:

    make INSTALL_HDR_PATH=/usr/include headers_install

The same goes for the toolchain instructions.
