[PATCH 1/3] autoconf/python_dev: pass include and library dir based on prefix

[Roger Pau Monne <roger.pau@citrix.com>]

NetBSD `python-conf --ldflags` doesn't return the library dir, so we
have to add it to LDFLAGS based on the prefix returned by `python-conf
--prefix`. Also the include dir has been added to CFLAGS using the
same technique.

If not passed the configure script fails on NetBSD, complaining it
cannot find lpythonx.x library during the python_dev test phase.

This is currently done on all OSes, since I think it's harmless to do
this on other systems also.
