I think the problem is not with the linker, but in your use of objcopy
to convert your ELF file to a raw binary file.

1) What arguments are you giving to mipsel-linux-objcopy?
i use objcopy as follow(the brec_flash is elf file)
        mipsel-linux-objcopy -O binary brec_flash brec_flash.bin

2) What is the output from mipsel-linux-objdump -h run on your
intermediate ELF object file?
i use mipsel-linux-objdump -h brec_flash and get messages as follow


brec_flash:     file format elf32-tradlittlemips
