[patch 2.4] menuconfig fix crash due to infinite recursion

[maks attems]

gawk(1) tells that getline "returns 0 on end of file and -1 on an error."
in current script for menuconfig if getline has an error,
it is still treated as true.

2.6 don't use that script anymore.
fix suggestion from Aharon Robbins <arnold@xxxxxxxxxx>
debian bts has 2 bugs open concerning that issue,
this is the one containing belows fix:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=147469

[TM] tested.
menuconfig still works for me. ;)
