How do you set the deployment target when compiling code for Apple TV? If I use -mios-min-version or -mmacosx-min-version I get:
% xcrun --sdk appletvos clang -isysroot $(xcrun --sdk appletvos --show-sdk-path) -mios-version-min=13.0 test.c
clang: warning: using sysroot for 'AppleTVOS' but targeting 'iPhone' [-Wincompatible-sysroot]
ld: warning: building for iOS, but linking in .tbd file (/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/SDKs/AppleTVOS15.0.sdk/usr/lib/libSystem.tbd) built for tvOS
ld: warning: building for iOS, but linking in .tbd file (/usr/lib/system/libcache.dylib) built for tvOS
ld: warning: building for iOS, but linking in .tbd file (/usr/lib/system/libcommonCrypto.dylib) built for tvOS
...
If I leave off the -mios-min-version then the code is compiled for the latest appletvos SDK however I want to target an earlier version:
xcrun --sdk appletvos clang -isysroot $(xcrun --sdk appletvos --show-sdk-path) test.c
otool -l a.out

There doesn't appear to be a -mtvos-min-version?
