Description

Starting arrow `6.0.1`, the `grpc-cpp` requirement was raised to `>=1.42.0,<1.43.0a0` which forces the GCC stack (`libstdcxx-ng`, `ibgcc-ng`) to pin to `>=11.2.0`.  

 

Prior to this change, the GCC stack was pinned to `>=9.4.0`.

 

Due to this change, many downstream libraries will have a conflict as many OSS libraries rely on if they rely on default GCC of LTS versions of OS's. Currently, Ubuntu 20.04 ships with gcc-9 and ubuntu 22.04 which will have gcc-11 as default is not out yet. The lastest `nvcc` 11.5 also doesn't fully support host compiler gcc 11.x for the same reason. Hence is it possible to relax arrow-cpp's `grpc-cpp` requirements so that it is also compatible with `libstdcxx-ng`/`ibgcc-ng`>=9.4.0 and release binaries for `6.0.1`?
