Did you read the GCC user manual and how the *position* of the -l parameters 
affect linking?

Go here:
<http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/Link-Options.html#Link%20Options>
and read about -l.

You should probably do:
avr-gcc -mmcu=atmega128 test2.c -lmyrobot
Do you see the difference?

And while you're there, you can read up on -L
<http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/Directory-
Options.html#Directory%20Options>
This tells GCC to search in other directories for libraries.

A lot can be found in the manuals.
