This is not a question about switching every one of my packages, or ubuntu-desktop (which I don't even use) to 64-bit.
I want to build just a couple programs in 64-bit. Is the answer different to the linked one above?

32-bit and 64-bit refer to the size of memory registers in a computer's CPU. How do you suppose a 32-bit kernel should do that?
- A 32-bit kernel can run 32-bit software.
- A 64-bit kernel can run 64-bit software and 32-bit software.
You need a 64-bit kernel to run 64-bit software.
The only way to use 64-bit software on a 32-bit system is with virtualization: install a 64-bit system into vBox or VmWare but that requires some support from your BIOS (You need enable Intel (R) Virtualization Technology and Intel (R) VT-d. More on this here: Can I use virtualbox with a 64 Bit image in a 32 bit host ).
