That is true. But as I explained when the comment was done the first time (and I
never got any answer), these files are generated in every exported directory.
Because the genwqe directory is now exported, the corresponding '..install.cmd'
and '.install' are generated.
See
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/Makefile.headersinst#n32
and
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/Makefile.headersinst#n130
for more details.

In other words, these files are there because some new directories are exported.
If those directories were added to the 'header-y' variable, the result would be
the same.

Nicolas
