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 

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.
