Hello world failed to AOT compile on "mono:latest"

[rdebath]

EDIT: See also: mono/mono#21515

I tried to compile a trivial program then process it using LLVM aot.
The error looks like this: mono/mono#18779
and this: dotnet/macios#7833

The non-llvm version of AOT works.

This still fails in the same way. Mono version now 6.12.0.122
