config.replaceCrossStdenv: add
Example with `clangUseLLVM` which is the default when using `useLLVM`
```nix
config.replaceCrossStdenv = { buildPackages, baseStdenv }:
if baseStdenv.targetPlatform.useLLVM or false
then (buildPackages.stdenvAdapters.overrideCC baseStdenv buildPackages.llvmPackages_16.clangUseLLVM)
else baseStdenv;
```
The conditional necessary, otherwise the other sets(such as `pkgsCross.aarch64-multiplatform.llvmPackages`)
without `useLLVM` will use the stdenv without the necessary conditions to avoid infinite
recursion because of [targetLlvmLibraries](https://github.com/NixOS/nixpkgs/blob/644b234e1c17aad539c03ac8020f831e20241d50/pkgs/development/compilers/llvm/16/default.nix#L208)
usage.
[`replaceStdenv` is not used when cross-compiling](https://github.com/NixOS/nixpkgs/blob/d77bda728d5041c1294a68fb25c79e2d161f62b9/pkgs/stdenv/cross/default.nix#L12-L13)
`replaceStdenv` uses an additional stage to replace the stdenv to avoid
infinite recursion and other issues but that should not be necessary for cross.
