cannot use `+=` on type `OrderedFloat<f64>`

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I would like to be able to use DataFusion on a Raspberry Pi running Ubuntu 20.04.3 but it does not compile.

$ cargo test
   Compiling datafusion v6.0.0 (/home/ubuntu/arrow-datafusion/datafusion)
error[E0368]: binary assignment operation `+=` cannot be applied to type `OrderedFloat<f64>`
   --> datafusion/src/physical_plan/tdigest/mod.rs:329:13
    |
329 |             weight_so_far += next.weight();
    |             -------------^^^^^^^^^^^^^^^^^
    |             |
    |             cannot use `+=` on type `OrderedFloat<f64>`

Describe the solution you'd like
I would like the code to compile.

Describe alternatives you've considered
It looks like I can use cross to cross-compile from my desktop to this architecture:

cross build --release --target aarch64-unknown-linux-gnu

I was able to get this to work on a different Raspberry Pi running the same OS. The only difference was 8 GB vs 4 GB memory. This doesn't make much sense to me but I am closing this issue.
