I am cross-compiling on x86_64 MacOS 11 for arm64 architecture. clang/XCode support it but I face an issue when external library is required. Let it be boost, for example. I know that the bottle for arm64 is available but it looks like there is no way to select it for installation.
arch -arm64 brew ... says that this architecture is unknown which sounds fair.
So the question is wheather there is an option to force brew install bottles for 'foreign' architecture ?
