Rollup merge of #116017 - Zalathar:darwin-stdlib, r=albertlarsan68
Don't pass `-stdlib=libc++` when building C files on macOS

When using *Command Line Tools for Xcode* version 15.0, clang will warn about `argument unused during compilation: '-stdlib=libc++'` if this flag is present when compiling C files only (i.e. no C++ files).

To avoid this warning, we can add the flag only to CXXFLAGS and not to CFLAGS.
