 This PR came up when I searched for math operation routines. The
 missing functions appear to still be missing in 10.0_BETA.

 $ nm /usr/lib/libm.so | grep remain
 000000000001cc80 T __ieee754_remainder
 000000000001cb70 T __ieee754_remainderf
 000000000001b530 T remainder
 000000000001b4c0 T remainderf

 I looked but could not find an automated test to cover this. If the
 long double remainder functions are a gap, does it make sense to add a
 test? It could be a shell script; the only wrinkle I can see would be
 stripped binaries with no symbols.
