make O="<dir>" install; output not relocated; 2.6.16.11(kbuild)

[Linda Walsh <lkml@tlinx.org>]

From "make help", the "O=" param to make is said to
 'Locate all output files in "dir", including .config'

I first did:
   "make O=$PWD/root bzImage modules"   # (Note: PWD=/usr/src/ast-261611)

That worked w/no apparent problems.

I wanted the output of "make install modules_install" placed
in a working directory (for transfer to the target system).

Instead, it appears the "O=" parameter is _partially_ ignored.

It is used for the "input" to the "make install" and the
"make modules_install", but seems to be ignored for "output":

ishtar:/usr/src/ast-261611> make V=1 O=$PWD/root modules_install
 make -C /usr/src/ast-261611/root \
   KBUILD_SRC=/usr/src/ast-261611 \
   KBUILD_EXTMOD="" -f /usr/src/ast-261611/Makefile modules_install
 mkdir: cannot create directory `/lib/modules/2.6.16.11-astarte':

   KBUILD_EXTMOD="" -f /usr/src/ast-261611/Makefile install
   make -f /usr/src/ast-261611/scripts/Makefile.build

     sh /usr/src/ast-261611/arch/i386/boot/install.sh 2.6.16.11-astarte 
arch/i386/boot/bzImage System.map "/boot"

     You may need to create an initial ramdisk now.

   Is this a bug or a feature?  I.e. is the "make help" misleading in
saying "O=<dir>" can be used to specify the output directory of a
make run?  Or should this be working?

Thanks,
Linda'
