Yes, ultimately the problem is that the mingw-gcc that is in the tarball git has a too low target. But that is a rather larger fix than setting the arch targetted in configure.

I think this might be a feature instead. As I wrote earlier, on
FreeBSD/i386, arch is set to i486 in GCC's configure script [1].
Hence, whatever version I install from the Ports Collection, it will
target i486 by default.
