I see. 

Testing similar functions I found that we have  
"undefined reference to `_llround'"
"undefined reference to `_llroundf'"

It seems that we are incorrectly looking in
newlib/libm/machine/spu

while the functionalities exist in
newlib/libm/common/s_llround.c
newlib/libm/common/sf_llround.c

llrint and llrintf have not such problem.
