Hello,

I am getting an undefined reference error for function `_atan2_fr16' when I try to use the function arg16 from the bfdsp library:

When I look at the toolchain build log I can see that the function has been compiled and included in the libbfdsp library:

if you actually read the source, you'll see it creats an _atan2_fr16 symbol, not atan2_fr16.
