That's weird since it's in fact linked with libcrypt, but doesn't seem to
use _any_ function/symbols from this lib:

thor# nm -D /bin/sleep
08049d1c A _DYNAMIC
08049cd4 A _GLOBAL_OFFSET_TABLE_
08049db8 B _IO_stderr_
08049db4 A __bss_start
         U __dcgettext
08049e0c B __environ
         U __gmon_start__
         U __libc_init_first
08049db4 A _edata
08049e4c A _end
08049e0c W _environ
08048ab8 A _etext
08048ac0 ? _fini
08048550 ? _init
08049e08 B _nl_msg_cat_cntr
08048670 T _start
         U atexit
         U bindtextdomain
08049e0c W environ
         U error
         U exit
         U fprintf
         U getopt_long
         U printf
         U puts
         U setlocale
         U sleep
         U textdomain
thor#
