[PATCH] Remove bashisms from scripts/extract-ikconfig

[Christian Kujau <lists@nerdbynature.de>]

Hi,

I noticed that scripts/extract-ikconfig is using /bin/sh in its shebang 
but when /bin/sh is not a symlink to bash, it breaks with:

# scripts/extract-ikconfig /boot/vmlinux
scripts/extract-ikconfig: 11: function: not found
scripts/extract-ikconfig: 12: typeset: not found

The diff below seems to fix this.
