web100clt: 3.6.5.2 - update to build on 10.9

With the new default secure strlcpy/strlcat functions in 10.9 web100clt no longer builds. In order to get it to build we need to set CFLAG -D_FORTIFY_SOURCE=0. This should be a temporary fix until it can be fixed upstream. 

I will follow up with upstream to see if this can be fixed quickly. Hopefully this pull request can be accepted in the interim. I believe the risk to be minimal given the client is generally run against servers the users trust.
