I don't think this is going to work.
Shared objects (.so) are quite tightly tied into the main executable. For
example they're likely to share memory structures, with no cleanly defined
interface between them. You're effectively asking qemu link together code
compiled for two (very) different targets into a single executable.
By contrast the linux syscall layer emulated by qemu-user is clean, well
defined, and relatively simple.
However, you should be able to run x86 mozilla with x86 plugins under qemu on
a PPC machine. I haven't tried this.
