Thanks all for useful hints. The way Chris suggested really works.
Here is the exact steps I took to build CURRENT release on STABLE box:

mkdir /usr/src4
cvs -R co -rRELENG_4 -d/usr/src4 src
mkdir -p /usr/src5/release
cvs -R co -d/usr/src5/release release
cd /usr/src4
make buildworld
cd release
make -f /usr/src5/release/Makefile release \
	     CHROOTDIR=/home/build \
             CVSROOT=/home/ncvs \
             WORLD_FLAGS=-j4 \
             ALLLANG=no \
             MAKE_ISOS=yes \
             DOCDISTFILES=/usr/ports/distfiles \
             NO_PREFETCHDISTFILES=yes \
             NO_PF=yes

However build was interrupted two times because of minor errors,
which was very easy to fix. First of all I added NO_PF=yes to
skip checking of existance of proxy user (I don't need PF).
The following two patches are fixing build problems.

It looks like some changes were made to sh syntax in CURRENT?
