Conditionalize which subdirectories we build, based on what configure

finds and what configure options are enabled.

Building with system OpenSSL doesn't quite work yet, still too many
hardwired paths in Makefiles.

+"""
+Hack to build our Python wrapper.  Basic problem here is that we need
+a bunch of arguments that were given to ./configure when Python itself
+was built, and there appears to be no real consistancy about how
+different unix-like distributions use the various parameters, so even
+the standard python-config script is not smart enough to figure out
+which arguments we need on every platform.  Feh.
+
+This script is an attempt to pull the relevant information out of the
+distutils.sysconfig module.  If I understood distutils better, I could
+probably figure out some way to wrap this whole thing up nicely in the
+distutils framework; if you understand how to do this, please do so
+and send me the code.
+
+As it is, this is a minimal hack to get the job done, and probably a
+bit fragile.  Much of the code is taken from python-config.  If
+there's any real documentation on how to do this sort of thing, I have
+not found it yet.  YMMV.  Beware Of Dog.
