As far as I can tell, you'll need to build it yourself; you need to
install a MinGW development environment anyway, and then you can use
it to build a recent gcc cross-compiler targeting
x86_64-unknown-linux-gnu.

Doing this properly will also require you to build a sysroot that has
a version of glibc installed in it; the easiest way to get one of
those is to take the glibc-devel packages from Fedora or Debian or
whatnot and extract them into the directory you set as --with-sysroot.
http://gcc.gnu.org/install/ will also discuss the prerequisites.

You'll still need the 32-bit MinGW to build VirtualBox; both are
needed at different points in the install.
