With mingw-w64-gcc 6.3.1-1, the x86_64 linker doesn't find the LTO plugin when building with -Wa,-mbig-obj. The i686 linker works fine. Example:

$ cat foo.c
int main() {
return 0;
}
$ i686-w64-mingw32-g++ -flto -Wa,-mbig-obj foo.c -o foo.exe
$ x86_64-w64-mingw32-g++ -flto -Wa,-mbig-obj foo.c -o foo.exe
/usr/lib/gcc/x86_64-w64-mingw32/6.3.1/../../../../x86_64-w64-mingw32/bin/ld: /tmp/ccbj2GZA.o: plugin needed to handle lto object
/usr/lib/gcc/x86_64-w64-mingw32/6.3.1/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o): In function `main':

Where does this come from? What package?

Edit: nevermind, got it.

mingw-w64-gcc is moved to AUR:
