2.6.22-rc3: regression: make M=$PWD modules_install does nothing

[Andrey Borzenkov <arvidjaar@mail.ru>]

This has been working up and including -rc2:

{pts/1}% sudo make -C ~/src/linux-git O=$HOME/build/linux-2.6.22 M=PWD V=1 
modules_install
make: Entering directory `/home/bor/src/linux-git'

modules_install

Makefile is trivial:
