I'm not familiar with uisng gdb over wire, but judging by 
http://sources.redhat.com/gdb/onlinedocs/gdb_19.html#SEC174 you need to 
make sure your GDB on the PC was configured and built with 
`--target=mips-idt-ecoff'.

the other choice may be to use the gdbserver program on the mipsel board 
to connect to gdb, but I'm not very familiar with that, really. I hope 
someof our mips hackers can chip in.

cheers,
