delete /bin and /sbin from stage2

["Shkarupa Xeniya" <ksenks gmail com>]

Hello!

If you know, please help to understand me this:

Why in upd-instroot this strings

1035         rm -rf $p/bin

1036         rm -rf $p/sbin

are present?

I have errors from mk-images, it calls buildinstall.functions

  33         $(/usr/sbin/chroot $root env LD_TRACE_PRELINKING=1 LD_WARN= \

  34                                      LD_TRACE_LOADED_OBJECTS=1 $LDSO $bin)

and I have been reported, there is no /bin/env

Best regards,
Kseny
