Every AMD64 processor is able to run 32-bit code as well as 64-bit code. However, a 32-bit application is unable to mix it with 64-bit libraries or vice versa. However, natively (without emulation) 32-bit applications can run if all shared libraries they need are available as 32-bit objects. Choose multilib support or not by selecting the according profile. The default is a multilib-enabled profile.
