Summary:
After building a target, subsequent builds of the same target do not perform preprocessing of the target's Info.plist file.

Steps to Reproduce:
- Create an iOS application project.
- Create a file in the same directory as the .xcodeproj file named 'InfoPlist.h', with contents:
#define FOOBAR Hello
- In the target build settings check 'Preprocess Info.plist File'.
- In the target build settings set 'Info.plist Preprocessor Prefix File' to 'InfoPlist.h'.
- In the project's Info.plist file add a new row with key: 'foobar' and value: 'FOOBAR'.
- Build the project.
- Find the Info.plist in the resulting app bundle.  Note that the value for the 'foobar' key is 'Hello'.
- Edit 'InfoPlist.h' to have contents:
#define FOOBAR Goodbye
- Build the project.
- Find the Info.plist in the resulting app bundle. Note that the value for the 'foobar' key is 'Hello'.

Expected Results:
In the last step above, the value for the 'foobar' key should be 'Goodbye'.

Actual Results:
The value for the 'foobar' key is still 'Hello'.

Regression:
In Xcode 3.2.6 preprocessing is performed every time a target is built so the 'foobar' key is always updated to contain the correct value.

Notes:
Performing a Clean and then building again causes the correct value to be embedded in the Info.plist file.  But subsequent builds repeat the same problem, until a Clean is performed again.
