You can but not using ports. emulators/linux_base-c6 is currently limited to
either i686 or x86_64 but not both: pkg-plist.* have conflicting entries.
This is partially documented in r393817. And consumer ports are all 32bit e.g.,
linux-c6-flashplugin11 has i386 distfile in distinfo.x86_64.
Alternatively, setting up a jail via sysutils/debootstrap or sysutils/rinse
for x86_64 then enabling multilib support should be easy. To use apps
outside of jail the dependencies must be under /compat/linux due to the way
path translation works (and hardcoded). It's also possible to build apps in
a mixed environment e.g.,
$ (export PATH=/compat/linux/bin:$PATH CFLAGS=-m32; cmake; gmake)
$ ./my_linux_app
Note1, in some cases you may need to bump compat.linux.osrelease sysctl.
Note2, to make 64bit OpenGL apps work with nvidia-driver you need to
patch linux64 ioctl handler and remove nvidia-modprobe.
Note3, 64bit CUDA apps may not work which also means no OpenCL or NVENC.

Yes.
