Eric Fiselier 0447bde044 [libunwind] Allow target flags to affect CMake configuration tests ... Summary: This patch changes the libunwind CMake so that it adds certain target flags like '-m32' or '--gcc-toolchain' before including config-ix.cmake. Since these flags can affect things like check_library_exists([...]) they needed to be added before the tests are performed. Additionally this patch adds LIBUNWIND_BUILD_32_BITS which defaults to LLVM_BUILD_32_BITS.
