The first approach mentioned, 'yes "" | make config', should work,
however. I'm doing it all the time. Well actually I'm calling

  yes "" | PAGER="cat -" make -C linux oldconfig

to anwer all questions 'Y' and to suppress blockings by 'more', as in
some rare cases oldconfig may decide to display the Configure.help
text.

Just touching autoconf.h gains, nothing, of course.
