I don't really see anything wrong with this, however I'd rather have
a compiler-based detection.
I.e. if the compiler define __MINGW32__ set the host to mingw (unless
set explicitly).
This should also address my other annoyance that you have to specify
--host when it really should be obvious that you are cross-compiling to
MINGW for example.
If nobody else cares about it I might work on it.
And if you have objections, now is a good time.
Because I've dropped enough variants of this because nobody cares even
though it's a constant annoyance as seen by the various issues and
different patches that all go back to our configure being too stupid
to figure out on its own what is compiling for even when it should be obvious.
