cdb41d5 doc: Install Rosetta on M1-macOS for qt in depends (Hennadii Stepanov) Pull request description: On master (c609e10) `make -C depends qt` on Apple Silicon based macOS 11.4 ends with an error: ``` /bin/sh: /Users/hebasto/bitcoin/depends/work/build/aarch64-apple-darwin20.5.0/qt/5.12.11-6c4d47a8f8f/qtbase/bin/moc: Bad CPU type in executable ``` Installing Rosetta 2 fixes it. Explanation. On Apple Silicon macOS the `qt` package in depends actually is cross compiled. All native tools (including `moc`) are x86_64 binaries, that require Rosetta 2 to run. ACKs for top commit: promag: ACK cdb41d5. fanquake: ACK cdb41d5 - I have not tested after installing Rosetta 2, but I saw the same issue during my first cross-compile on an M1 box.

make -C depends qton Apple Silicon based macOS 11.4 ends with an error:Installing Rosetta 2 fixes it.
Explanation. On Apple Silicon macOS the
qtpackage in depends actually is cross compiled. All native tools (includingmoc) are x86_64 binaries, that require Rosetta 2 to run.
