Why can not install kernel headers?

[mobile.parmenides]

I am reading an article about kernel header installtion, its links as follows:
http://lxr.linux.no/#linux+v2.6.32/Documentation/make/headers_install.txt#L11

Following a command given by the article:
make headers_install ARCH=i386 INSTALL_HDR_PATH=/usr/include
the kernel headers should be installed into '/usr/include'. However, when checking
'/usr/include/linux' and '/usr/include/asm', I found actually these kernel headers have
not installed (by checking timestamps).

In fact, kernel headers have be installed into 'include' subdirectory of kernel top-level
directory. Obviously, the 'INSTALL_HDR_PATH' parameter in the above command
does not take effect. Is there any way to deal with the problem? If I have to use 'cp' to
install headers by hand, the 'INSTALL_HDR_PATH' seems not to play its roles.

The following contradicts the examples in
Documentation/make/headers_install.txt, but in my case (android tree),
the make command creates an 'include' subdirectory in $INSTALL_HDR_PATH.
That is, if I do
make INSTALL_HDR_PATH=/path/to/headers/ headers_install
Then, the headers are installed into /path/to/headers/include.
