Description
Asking the AOT compiler to use LLVM fails with the ios-arm RuntimeIdentifier:

The option was renamed in newer LLVM, so this line needs to be changed:
runtime/src/mono/mono/mini/aot-compiler.c
Line 1152 in d40fbf4
I think the new name of the option is
-mframe-pointer=all.steveisok commentedon Aug 25, 2021

[iOSCoolApp] Build only for ios-arm64, due to dotnet/runtime#58112.
Port samples used for submission tests to .NET. (#38)

Looks like the replacement flag is
-frame-pointer=all:dotnet/llvm-project@b7cef81
