[jira] [Created] (ARROW-18255) [C++] Support armv6

Maarten Pronk created ARROW-18255:
-------------------------------------

             Summary: [C++] Support armv6
                 Key: ARROW-18255
                 URL: https://issues.apache.org/jira/browse/ARROW-18255
             Project: Apache Arrow
          Issue Type: Improvement
    Affects Versions: 10.0.0
            Reporter: Maarten Pronk


Over at [https://github.com/JuliaPackaging/Yggdrasil/pull/5425,] we cross-compile Arrow to make it easily available within the Julia ecosystem. This will for example enable a GDAL with Arrow/Parquet driver support that can be installed for everyone.

We noticed when going from v9 to v10, `armv6` (or any non-defined cpu architecture really) now gives an error when compiling. The change is in `cpp/cmake_modules/SetupCxxFlags.cmake`. We now patch the code by giving armv6 the same status as armv7, which seems to work.

Would it be possible to not error out on unknown platforms? A warning with this platform is not officially supported could be an alternative. Or, the other way, you could confirm that armv6 (and others) are just _really_ unsupported (as in probably breaking) and we should not attempt to compile for those platforms?
