Changes to Jambase for backward-compatibility

I just checked in a few provisional changes to Jambase in the
boost_build_v2 branch so that the "jam" executable we build can be used
as a drop-in in the current (v1) build system:

if [ MATCH .*(bjam).* : $(ARGV[1]:B:L) ]
+ || $(BOOST_ROOT) # A temporary measure so Jam works with
Boost.Build v1
{
# Another temporary measure so Jam works with Boost.Build v1
+ BOOST_BUILD_PATH ?= $(BOOST_ROOT)/tools/build ;

These two lines can be eliminated when we release v2. In the meantime,
they should allow us to move the code for the new startup behavior back
to the main trunk without interrupting anyone's work.
