Summary:
when run "llvm-ar cr" on AIX OS , it created a gnu archive, it is not desirable in aix OS.
instead of creating a gnu archive, the patch will print a unsupport message for llvm-ar big archive write operation in AIX OS.
after implement the big archive operation, I will revert the XFAIL: AIX " and "--format=gnu" test cases in the patch.
