I submitted a fix for this a while ago, not sure why it hasn't been
checked in (I don't have write access to vger).  Here's the patch.  I
have tested this on both PPC and x86, and it works for me--I have not
had any problem with make xconfig for a while.  If someone could check
this in to vger I'd appreciate it (and so would a bunch of other
people).
