I'd look at the output from “eu-readelf -s /opt/cross/lib/gcc/arm-linux-gnueabihf/6.2.0/../../../../arm-linux-gnueabihf/lib/libstdc++.so” next. It seems to me it contains a statically-linked copy of libm.a, which really should not happen. Since you are using a pre-built sysroot, maybe that's not set up for dynamic linking at all?
