4ea83bf562 uclibc insists on having 70k static buffer for crypt.
For bbox it's not acceptable. Roll our own des and md5 crypt
implementation. Against older uclibc:

   text    data     bss     dec     hex filename
 759945     604    6684  767233   bb501 busybox_old
 759766     604    6684  767054   bb44e busybox_unstripped

so, we still save on code size.
