    I see maskray set COMPILER_RT_CRT_USE_EH_FRAME_REGISTRY OFF
https://github.com/llvm/llvm-project/pull/83201

but it was reverted, and no reason
https://github.com/llvm/llvm-project/pull/84580 

libunwind not compile __register_frame_info in default

I think this would lead to a situation where the compiler-rt's crtbegin.o file contains the __register_frame_info symbol, but libunwind does not provide it by default.
