The data service didn't show any changes in derivations associated with
this change, so I've gone ahead and pushed it to master as
a795a02a9d988be5a762886620f7bb6a95e7ffdb.

It did show some changes, but they related to gexp's in the builder
script for icu4c-70 when built for riscv64. I fixed that in
b1e9ae7f0e72bc3c8c7ab28362315fac5dfb65fe.
