You just point to it afaics. (you specify the correct python binary).
But never tried it myself. Default should be python2 anyway.

But if you want to do python2 and 3 in parallel, you need a hack. What I do here
is:

1602 ifeq "$(BUILD_PYUNO)" "y"
1603   ifeq "$(ENABLE_PYTHON3)" "y"
1604         # FIXME: won't work when pyuno is migrated to gbuild as all is directly in solver
1605         # then...
1606         rm -rf $(SOURCE_TREE)/pyuno-py3
1607         cp -ra $(SOURCE_TREE)/pyuno $(SOURCE_TREE)/pyuno-py3
1608         cd $(SOURCE_TREE)/pyuno-py3; \
1609                 rm -rf $(shell . $(SOURCE_TREE)/Env.Host.sh; echo $$OUTPATH$$PROEXT); \
1610                 . $(CURDIR)/$(SOURCE_TREE)/Env.Host.sh; \
1611                 PATH=$(BUILD_PATH) PYTHON=$(PYTHON3) PYTHON_CFLAGS=$(shell pkg-config --cflags python-$(PY3MAJOR).$(PY3MINOR)mu) PYTHON_LIBS=$(shell pkg-config --libs python-$(PY3MAJOR).$(PY3MINOR)mu) \
1612                 ../solenv/bin/build.pl  # NO DELIVER!
1613   endif
1614 endif

+ other stuff to reuse python2s files if the same and install python3
stuff manually.

(see http://anonscm.debian.org/gitweb/?p=pkg-openoffice/libreoffice.git;a=blob;f=rules;h=1a35e8ee8d0ff3de5d495a036197355b784269f1;hb=refs/heads/debian-experimental-3.5 and look for ENABLE_PYTHON3 stuff)
