[libc-commits] [libc] [libc] Include CheckCXXCompilerFlag when checking compiler features (PR #118862)

[Tristan Ross via libc-commits]

https://github.com/RossComputerGuy created https://github.com/llvm/llvm-project/pull/118862

Includes `CheckCXXCompilerFlag` so when building LLVM libc is built standalone, it actually works and doesn't complain about `check_cxx_compiler_flag` not being defined.
