I strongly disagree with this, please preserve the old behaviour. It took 
a while to work out the current behaviour.
Only silentoldconfig checks for stdin because it's used as hook during 
kbuild to verify the config. For all other interactive targets the user 
has to know what he's doing, e.g. it's valid to do "yes '' | make 
oldconfig".

This isn't yet in aconf.c.
