[patch 8/8] scripts/extract-ikconfig: remove bashisms

[akpm@linux-foundation.org]

From: Werner Almesberger <werner@openmoko.org>

scripts/extract-ikconfig contains a lot of gratuituous bashisms, which
make it fail if /bin/sh isn't bash.  This patch replaces them with regular
Bourne shell constructs.
