Upgraded to Xcode 4.3, got missing cpp

Xcode upgrade to 4.3 had bitten me again, it removed the workaround for cpp compiler that I had to put in awhile back.

In this case I was building libcurl and got this error:
./configure: line 2062: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp: No such file or directory

sure enough the workaround as I posted before (Native libraries porting to iOS) is to create the missing symbolic link in the /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin directory:
ln -s llvm-cpp-4.2 cpp
