I also get this error when trying to build on Windows.  I installed 
mingw-w64 using the installer found here:

http://mingw-w64.org/doku.php/download/mingw-builds

I just noticed that the host gets auto-detected as "x86_64-pc-mingw64" 
(same as you specified explicitly).  I see that when building on mingw, 
-Wno-format should be added, specifically ignoring these warnings:

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=bfd/warning.m4;h=5a7f92d61622c6a0934aa950f8aaa6bf55677d43;hb=HEAD#l75

However, it's only done when the host string contains "mingw32", not 
"mingw64".  Maybe this needs to be adjusted to "*-*-mingw*"?  If you 
grep, you'll find a bunch of other things conditionally done if the 
triplet is "*-*-mingw32*", maybe they need to be adjusted too?
