6c6b78126a Construct a correct value of PYTHONHOME from the interpreter
running SCons, make it into a sticky option that can be
overridden at build time, and set it up before the interpreter
is started.  Also, fix the code that turns sticky options into
config/*.hh so that it works with types other than bool.
