What's in these .so files? What created them? Try the 'file' command, which will tell you whether they are indeed linkable binaries.
If they're shared libraries (in which case, the Mac OS X convention for file extension is '.dylib", not ".so"), then they should probably follow, rather than precede, your object files on the link line. And there don't seem to be any object code input files (.o or .a). And the output of the linker is normally either a static archive (.a) or a dynamic library (.dylib), or the executable for an app or command-line tool.
So let's start from "What are you really trying to do?"
I had a workshop all of last week, so my linking problem went on the back-burner.
The problem I have with isolating an example is that people will remain intent on trying to find a workaround for the example. I am trying to learn how to interpret this linker message. All the .so files that I include in the linking have been built with the same gcc/ld and using the same CFLAGS and LDFLAGS variables.
The call to gcc I posted is generated by a compiler under development, that compiles a high-level language down to c and hands that to gcc. This is what I'm trying to do. Some of the intermediate results are built to a /tmp/... directory, i.e. all referenced code in /tmp/... is code from the same build-cycle.
Since you're not passing an -arch flag to ld, the output defaults to the architecture on which ld is running. The error is telling you that a binary component for that architecture does not exist in the input libraries. For instance, if you're running on Intel, but the libraries are PPC-only.
