SubjectPatch for Menuconfig script
This is just a patch to the Menuconfig script (can be easily adapted to 
the other ones) that allows you to configure the kernel without the
requirement of bash (I tested it with ksh, in POSIX-only mode). Feel
free to flame me :P

(Yes it is kinda big, but that's because I had to hack a bunch of parts
with it)
