When Clang is used as a cross compiler, it should respect the target platform default. Defaulting to a configure-time CLANG_DEFAULT_STD_C/CLANG_DEFAULT_STD_CXX does not make much sense. When Clang is used as a single-platform compiler, we should use Clang configuration file (https://discourse.llvm.org/t/configuration-files/42529 https://clang.llvm.org/docs/UsersManual.html#configuration-files). The Gentoo needs from D34365 has been satisfied by a configuration file. Reviewed By: mgorny Differential Revision: https://reviews.llvm.org/D133375
