When you run `ldconfig -p` you get "unknown" for the .so variant on all 64bit libs. $ ldconfig -p | tail libcrypt.so.1 (unknown) => /lib/libcrypt.so.1 For more info see here http://forum.tinycorelinux.net/index.php/topic,21344.0.html
In the linked thread there is a patch. http://patches.tinycorelinux.net/uploaded/uclibc-ldconfig-x64-p-option.patch
