Thanks for working on this, Bruno!

This would be a useful feature to us, too.

I am wondering if there is clearer name than `-gen-reproducer`.

IIUC, the goal is to extract all environment (system) dependent pieces, copying them to a folder where the compiler can be chroot-ed (via `-isysroot`). In some sense, what we do seems close to what `-header-include-file list_of_includes.txt` does and additionally copying the contents of the list_of_includes.txt (and possibly mounting a vfs overlay).
