The bins are packaged into -dev. In the rpm version, i see it packaged

$ rpm -qlp ./tmp/deploy/rpm/aarch64/grpc-dev-1.35.0-r0.aarch64.rpm | 
grep grpc_cpp_plugin
/usr/bin/grpc_cpp_plugin

And same way they're to see

  ls -l ./tmp/work/*/*/*/recipe-sysroot-native/usr/bin/*grpc*

The executables seem only be useful for dev and thus only as native. At 
this point it seems it's about going deep into debugging your recipe, as 
seems there's no solution laying on the surface.
