It's telling you that you have too many duplicate definitions of '__ltsf2'. In the code. If they are all the same, you can find them and #ifndef them.

If you search the web on "multiple definition of __ltsf2" you will find several references and solutions. The most common solution is to include "-lm" a second time in the avr-gcc command in your make file. See search results for more detail.
