[PATCH] Fix LOCALVERSION append plus logic

[<alan.tull@freescale.com>]

From: Alan Tull <alan.tull@freescale.com>

This change fixes the logic to do what the comment says
when CONFIG_LOCALVERSION_AUTO and CONFIG_LOCALVERSION are
both not set.

Also fix a spelling error in the comment.

If the kernel tree is in git, here's the config
permutations (with CONFIG_LOCALVERSION_AUTO turned off)
and the image name resulting:

CONFIG_LOCALVERSION=""
results:
patched   :   Linux-2.6.35.3+
unpatched :   Linux-2.6.35.3

CONFIG_LOCALVERSION="-something"
results:
patched   :   Linux-2.6.35.3-something
unpatched :   Linux-2.6.35.3-something+
