No component `cpp` (e.g. `x86_64-w64-mingw32-cpp`)

The GCC based mingw (that can be installed from Linux repo) has a cpp for each arch.
For example x86_64-w64-mingw32-cpp, i686-w64-mingw32-cpp.
Some build script may rely on this command.

But your llvm-mingw lacks this command.

Indeed, that's missing. In principle this could just be more or less a forwarding command to clang. But it seems like clang doesn't have built-in support for mapping a <prefix>-cpp tool name to the right mode of operation, like it has for a few other cases: https://github.com/llvm/llvm-project/blob/llvmorg-20.1.7/clang/lib/Driver/Driver.cpp#L294-L308 So this would maybe require custom support in our wrapper scripts/executables then.

Can you specifically point to a build system/script that does require this?
