compiling for ppc only... no i386

All, I'm using Xcode 2.2.1, and Tiger 10.4.8. I have an application that uses MySQL. I've been building this app under debug for many months. Now I'm trying to do a release build. However, Xcode is trying to build a universal binary, creating object files in both a ppc and i386 directory. In my project settings, I have "Architecture" value set to "ppc". That's the only entry. How do I make Xcode compile for PPC only? The reason for the failure is that I don't have any i386 MySQL code on my machine, so I get unresolved symbols.

This doesn't happen when compiling under debug, and the differences in customized settings is minor:

Debug:
SDK Path : /Developer/SDKs/MacOSX10.4u.sdk
Prebinding: (unchecked)
Mismatched Return Type : (checked)
Unused Variables : (checked)

Release has the same settings, plus:
Architectures : (ppc) (although I can delete this value so that Architectures has no entries, and the result is the same
User Header Search Paths : /usr/local/mysql/include
Library Search Paths : /usr/local/mysql/lib
Mac OS X Deployment Target : Mac OS X 10.4
Instruction Scheduling : None


How do you prevent Xcode from attempting to make an i386 exe?

Thanks,
Eric
