looking at the grpc_cli linking error on Linux x86_64 (log):

/home/linuxbrew/.linuxbrew/lib/libupb.a(extension_registry.c.o): undefined reference to symbol '__stop_linkarr_upb_AllExts'
  /usr/bin/ld: libupb_mini_table_lib.so.48.0.0: error adding symbols: DSO missing from command line

it seems related to protocolbuffers/protobuf#21755

That's a bit of a rabithole. @scpeters am I correct in thinking there is no usable patch there for us and we might have to wait until 32 (potentially this month).

it is indeed a rabbithole. It sounds like there might not be a fix in 32, and I commented in protocolbuffers/protobuf#21755 (comment) to clarify

Is there an easy way to reproduce the error? If so then I could take a look. I kind of suspect it is not related to protocolbuffers/protobuf#21755 despite the similar error message, because we have been using linker arrays on Linux for a while with no issues. I would guess that something else is going wrong with the way the linker command is set up, like perhaps an ODR violation.

I think this should get you started building this PR, if you don't have Homebrew installed on linux you can also use our docker container:

brew update
cd $(brew --repo homebrew/core)
git checkout bump-protobuf-31.1
export HOMEBREW_NO_INSTALL_FROM_API=1
brew install --build-from-source grpc

Rolling this into #227169.
