There are 13 section headers, starting at offset 0x386c:

$cat foo.lds
OUTPUT_ARCH(mips)
ENTRY(Init)
SECTIONS
{
	.text 0xc0000000 :
	{ *(.text) *(.rodata*) }
	.data :  { *(.data) }
 	.bss  :  { *(.sbss) *(.scommon) *(.bss) *(COMMON) }
}

I invoke the following command to create foo.out
$mips-elf-ld -EL -n -r -T foo.lds -o foo.out $(OBJS)
