So now we can either run 'make test' with --enable-selftest and without?

I wouldn't want us to rely on LD_PRELOAD totally (very
platform-dependent), but being able to test the binaries that a
distribution such as debian or Fedora ship, which shouldn't be compiled
with --enable-sefltest is a really big win!  

Beyond that, I look forward to being able to test things like bind, as
well as being able to force system libraries via socket_wrapper, so we
don't feel the need to reimplement them all.  (could allow testing of a
future MIT krb5 based Samba AD KDC).

Well done!
