you have to use lipo tool to glue ppc and i386 together
(see man lipo)
so you have to call gcc compiler twice
one time for ppc (-arch ppc)
and one time for i386 (-arch i386)
hope it will help

I've read technote 1295 (http://developer.apple.com/qa/qa2005/

(building a JNI Universal application), but I'm still having
trouble creating a jni library that works on both PPC and Intel
hardware.
I don't actually have an intel machine, so that makes debugging
more difficult for me. But I have created a jni library in the JDIC
project which implements the TrayIcon API for Mac OS, and it works
great on my G4 machine.
However, it gives an UnsatisfiedLinkError when run on an Intel box.
My jni library is composed of 6 source files, and I am compiling
them via a shell script that is invoked via an ant task. The
contents of the shell script are simply:
gcc -std=gnu99 -c -arch i386 -arch ppc -isysroot /Developer/SDKs/
MacOSX10.4u.sdk -I/System/Library/Frameworks/JavaVM.framework/
Headers -I/System/Library/Frameworks/Cocoa.framework/Headers *.m
gcc -dynamiclib -o ../libtray.jnilib *.o -framework JavaVM -
framework Cocoa
Am I missing something?
Thanks,
