2. https://github.com/llvm/llvm-project/issues/101657
The complete changes for porting are present in this draft PR:
https://github.com/llvm/llvm-project/pull/102601

Adding changes for minimal build for lldb binary on AIX. 
getopt.h is missing in AIX, so instead relying on LLDB's getopt functions.
