Summary: In support of IBM's efforts to produce a viable C and C++ LLVM compiler for AIX (ref: RFC at http://lists.llvm.org/pipermail/llvm-dev/2019-February/130175.html), this patch adds customizations to the CMake files in order to properly invoke the host toolchain for the build on AIX. Additional changes to enable a successful build will follow. Patch by Xing Xue Reviewers: hubert.reinterpretcast, jasonliu, sfertile Reviewed by: hubert.reinterpretcast Differential Revision: https://reviews.llvm.org/D58250 llvm-svn: 356104
