Print out PATH after stripping out the directories inserted by the XCode app.
This is called when we issue a waf build from within XCode because the paths inserted by
XCode interfere with our tintin build. 

When you issue a build from within XCode, it calls into the waf-xcode.sh script. That script
calls this script in order to strip out the XCode directories from PATH before it transfers
control to waf.
