    I the GO_IF_LEGITIMATE_ADDRESS address macro i am allowing this
address because the target supports symbolic address in QImode for
store operations.

If your target can not use a symbolic address in a QImode load, then GO_IF_LEGITIMATE_ADDRESS must reject symbolic addresses in QImode. It's that simple.
