[uClibc] Shooshing up mkfs.jffs2 in jffs2root.mk

[Mitch Davis]

Hello uClibc people,

Not using JFFS?  When you type "make", do you get a message
like this?

  host [~/buildroot] make
  which: no mkfs.jffs2 in /home/mjd/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/sbin:/usr/sbin:/home/mjd/bin)
  [blah blah]

Here's a patch:
