No. No no no no no!
Under _zero_ circumstances should you touch autoconf.h. Even kernel
developers _don't_ touch it, even for a quick fix. If you want to
do such quick fixes (not recommended anyway) edit .config _and_then_run
make_oldconfig_. BUT, you should really be using 'make menuconfig' or
'make config' in any case.
If you have an existing configuration, 'make *_config' has no effect.
You need to remove .config first for it to have an effect. (make *_config
just changes the default configuration, not the current configuration).
I'm considering making it remove .config through so that the above
sequence of commands works.
