This would not be kind.  I expect that config.sub gives the proper
triplet when doing ./config.sub mingw32.  Or am I not understanding you?

The reason ./config.sub mingw32 returns the proper triplet is because
historically people, including many developers, have no idea what
i386-pc-mingw32 means when GCC and binutils creates a directory so
--host=mingw32 is given to create a mingw32 directory instead.
