I have tried to build jextract (https://github.com/openjdk/jextract/tree/jdk22) with LLVM (https://github.com/llvm/llvm-project/releases/download/llvmorg-16.0.4/clang+llvm-16.0.4-powerpc64-ibm-aix-7.2.tar.xz). I noticed that llvm mainly consists of .a files. So, I think we need to support that for FFI compatibility with other libraries and open source projects.
