Yes, that is it and another line is x86_64 only (arch_name is):

     if (image == NULL) {
+#if defined(x86_64_HOST_ARCH)
         errorBelch("%" PATH_FMT ": failed to allocate memory for image",
                    arch_name);
+#endif
         return NULL;

I would like to take the chance to ask a question:
How can I configure to build x86_64?

When I build GHC (with msys2), it always builds i386 and I haven't spotted
the option in ./configure to choose a x86_64 release.

Thanks,
