build system broken in 2.6.6rc1 for external modules?

[Arkadiusz Miskiewicz]

On 2.6.5 this works fine (/usr/src/linux is read only and make mrproper'ed):

ln -sf %{_kernelsrcdir}/config-up .config
install -d include/{linux,config}
ln -sf %{_kernelsrcdir}/include/linux/autoconf-up.h include/linux/autoconf.h
ln -sf %{_kernelsrcdir}/include/asm-%{_arch} include/asm
touch include/config/MARKER
%{__make} -C %{_kernelsrcdir} scripts modules \
        SUBDIRS=$PWD \
        O=$PWD \
        V=1

I'm getting:

+ cp -r drivers drivers-smp
+ cd drivers

and so one

but on 2.6.6rc1

So what's new way of building external modules when sources are read only?
