Thanks for the report.  Here's the right place to go.

This warning is very suspicious.  It causes the build failure.
Question is what caused the warning ...

Can you please post the contents of /mingw/etc/config.site
and the output of
  ./libtool --config

You might also want to retry building without a cache or site file in
sight (rm config.cache; CONFIG_SITE=/dev/null ./configure) and see
whether that changes the failure.

Thanks,
Ralf
