The simulators in GDB were mostly designed to allow the compiler
writers to test their code. Therefore most simulators don't implement
all of the instruction set, and don't have any device support.
Some simulators are more complete. As Andrew says, the TX39 simulator
is fully functional, as is the PowerPC simulator, although you have to
configure it correctly.
If you cannot use the Linux synthetic target, then an alternative is
to use a PC emulator like Bochs or Qemu. Just treat it like a PC and
build eCos to boot from floppy.
