Subject: [PATCH] install-wrappers: Install wrappers named <target>-llvm-ar and
 <target>-llvm-ranlib

This is necessary for CMake to detect working IPO (LTO); if the
compiler is named <target>-{gcc,clang}, CMake expects to find
matching tools named <target>-llvm-{ar,ranlib} too. (The CMake
module CheckIPOSupported and function check_ipo_supported expects
to have CMAKE_LANG_COMPILER_AR and ..._RANLIB set to working tools;
the Clang-FindBinUtils.cmake module looks for tools named
llvm-ar/llvm-ranlib with the same prefix as the compiler.)
