I'd long forgotten I even opened this ticket... and guess I have no confidence
that it will ever be fixed given no one has accepted it in 2 years....

In the meantime you can use srec_cat to output Verilog Hex (VMEM) formats. 
Here's an example of our Makefile targets:

$(BUILD_DIR)/$(BIN).hex: $(BUILD_DIR)/$(BIN).elf
        @echo "  IHEX    $(notdir $@)"
        $(CMD_ECHO) $(OBJCOPY) -O ihex $< $@

$(BUILD_DIR)/$(BIN).32.vmem: $(BUILD_DIR)/$(BIN).hex
        @echo "  VMEM    $(notdir $@)"
        $(CMD_ECHO) srec_cat $< -intel \
                -fill 0xFF -within $< -intel \
                -range-pad 4 \
                -crop $(START) $(END) \
                -offset -$(START) \
                -byte-swap 4 \
                -output $@ -vmem 32

$(BUILD_DIR)/$(BIN).128.vmem: $(BUILD_DIR)/$(BIN).hex
        @echo "  VMEM    $(notdir $@)"
        $(CMD_ECHO) srec_cat $< -intel \
                -fill 0xFF -within $< -intel \
                -range-pad 16 \
                -crop $(START) $(END) \
                -offset -$(START) \
                -byte-swap 128 \
                -output $@ -vmem 128
