.bin image too large for QEMU to load

I generated the .bin file for a very simple .s .c and .ld files for cortex m4 (STM32). The .c file has 3 lines of code:

int c_entry() {
  return 0;
}

Assembler file is as below:

.section isr_vector, "x"
.syntax unified
.global _Reset
_Reset:
  .word 0
  .word  Reset_Handler /* Reset */
  .word  NMI_handler
  .word  HardFault
  .word  MemManage 
  .word  BusFault 
  .word  UsageFault 
  .word  0 /* Reserved */
  .word  0/* Reserved */
  .word  0/* Reserved */
  .word  0/* Reserved */
  .word  SVCall 
  .word  DebugMonitor 
  .word  0/* Reserved */
  .word  PendSV 
  .word  SysTick 

Reset_Handler:
  LDR sp, =stack_top
  BL c_entry
  B .
NMI_handler:
  B . /*NMI_handler*/  
HardFault:
  B .
MemManage:
  B .
BusFault:
  B .
UsageFault:
  B .
SVCall:
  B .
DebugMonitor:
  B .
PendSV:
  B .
SysTick:
  B .

And linker file is :

ENTRY(_Reset)

MEMORY
{
  FLASH (rx)      : ORIGIN = 0x08000000, LENGTH = 512K
  RAM (xrw)       : ORIGIN = 0x20000000, LENGTH = 128K
  CCMRAM (rw)     : ORIGIN = 0x10000000, LENGTH = 64K
  PERIPHERALS(rw) : ORIGIN = 0x40000000, LENGTH = 128K
}

SECTIONS
{

 .startup . : { stm32.o(.text) } >FLASH
 .text : { *(.text) } 
 .data : { *(.data) } >RAM AT> FLASH
 .bss : { *(.bss COMMON) } >RAM
 . = ALIGN(4);
 . = . + 0x400; /* required amount of stack */
 stack_top = 0x20020000;
}

I generate the .elf using the command below:

arm-none-eabi-ld -T stm32.ld stm32src.o stm32.o -o stm32.elf

And then .bin file by running:

arm-none-eabi-objcopy -O binary stm32.elf stm32.bin

The generated .bin file is 131MB which is not accepted by QEMU and generates error in the image below:

Why such a simple program generating such a huge bin file?

EDIT: I have removed the canberra-gtk error (showed in the image)
