Faster Floating Point Arithmetik for the ATMEL

Floating point routines for addition, subtraction, multiplication are delivered with the library, e.g from http://download.savannah.gnu.org

There in avr-libc-1.4.5/libm/fplib are the source codes addsf3.s, mulsf3.s and divsf3.s

HJHerbert replaced these routines by home/cc/lq/_addsf3.s, home/cc/lq/_mulsf3.s and home/cc/lq/_divsf3.s, which are compatible and faster.
