Are the headers files already sanitized inside the kernel tree or are they
generated on-the-fly by "make headers-install" command ?
If the last, the tools used to generate the headers files (the ones in /tools
for the first build, but the ones in /{bin,usr} in iterative builds) could
have some impact on how they are generated and what contains each one.

In the chapter05 phase when the linux kernel headers are installed
the /tools/include directory already contains headers from binutils-pass1
build, thus the "cp" method is used to not delete them.

To switch to the "cp" method in chapter06 would be the most failsafe solution,
but for jhalfs to work that change should be done in the book. If not, the
most simple is to skip the headers reinstallation, if we are sure that that
will have no impact on the comparative analysis.
