You are not supposed to run cross compiled executable files. This is not
even a linker error.

Do not guess, there is nothing to infer from it, it is done on purpose.
You will need to copy these to where your executable programs are
running. Additionally, you mustn't mix DLLs from different toolchains,
so in this case, take the dll from i686-pc-mingw32.
