[PATCH v3 2/4] meson: Warn when TCI is selected but TCG backend is available |
Date: |

Some new users get confused with 'TCG' and 'TCI', and enable TCI
support expecting to enable TCG.
Emit a warning when native TCG backend is available on the
host architecture, mentioning this is a suboptimal configuration.
