Not wrapped into a nice macro yet, but INN currently uses the following in
order to get the paths needed to embed Python.  Python 2 has a nicer way
of handling this, but the following works with both 1.5.1 and 2.

dnl Libraries and flags for embedded Python.
dnl FIXME: I wish there was a less icky way to get this.
