Given that llround and llroundl are POSIX APIs, I wonder if they shouldn't
be in libc/include/math.h like everything else, just defined for SPU only
for now.  Eventually this API should be available for all targets.

The strtold patch in stdlib.h should be accompanies by a matching patch
for wcstold in wchar.h, probably.

Other than that, I guess we should wait for Jeff.  I'm not feeling
confortable to check this in.  But thanks for providing this patch.
