You need to mount /libexec into your jail and /usr/lib32 into the /usr/lib. 
This will get the base system in your jail working. You also need to symlink 
/usr/lib32 → /usr/lib, because it appears that is hard-coded location in 
ld-elf32.so.1.

To compile ports in the jail you have to define ARCH=i386 in the make.conf of 
the jail, because it defaults to the kernel arch amd64. This will get a lot of 
ports to compile into proper i386 binaries and libraries. But there are ports 
I have not managed to build, such as wine and perl. The binaries from the wine 
package just dump core inside my jail. I suppose wine simply interacts to 
closely with the kernel.

Why perl doesn't build, I don't know. It's my impression that some ports just 
don't manage to see the libraries they just built. I have no idea, why, though.

For some ports you have to add --host=i386 and --build=i386 to the 
CONFIGURE_ENV, because configure thinks you're trying to crosscompile and 
looks for the cross-compiling tools.
