Removing /usr/lib32 on AMD64

I'm not sure I was ever given the option to deselect it during 
sysinstall. I don't rememeber any obvious question at least and 
/etc/src.conf did not exist efter install.

There are references in ldconfig to a couple of options I find in 
/etc/defaults/rc.conf

ldconfig32_paths="/usr/lib32" # 32-bit compatibility shared library
ldconfig_local32_dirs="/usr/local/libdata/ldconfig32"

Should I blank those? /usr/local/libdata/ldconfig32 is an empty folder here.

There's also a /libexec/ld-elf32.so.1 left, with the same old date as 
the libs, and a symlink from /usr/libexec/ld-elf32.so.1 pointing to it. 
Should I leave them or remove them? They were not mentioned in the diff 
in the bugreport.
