[PATCH 2/2] busybox: add grep to temporary links during uninstall

[Paul Eggleton <paul.eggleton@linux.intel.com>]

In the busybox package prerm we set up some temporary links and modify
PATH so that certain utilities are provided for the purpose of running
update-alternatives; if grep is not among these then you get errors when
removing busybox, so add a temporary link for grep as well.
