That's not right.  You can't use '||' in config language.  (Try it
with xconfig some time.)  You have to either nest if statements or
make use of precedence.  Documentation/kbuild/config-language.txt
doesn't actually specify the precedence, but in the Unix test(1) from
which it is derived, AND binds tighter than OR.  Thus:

  if [ "$CONFIG_SND" != "n" ]; then
     if [ "$CONFIG_SPARC32" = "y" -o "$CONFIG_SPARC64" = "y" ]; then
        source sound/sparc/Config.in
     fi
  fi

-- or --

  if [ "$CONFIG_SND" != "n" -a "$CONFIG_SPARC32" = "y" -o \
       "$CONFIG_SND" != "n" -a "$CONFIG_SPARC64" = "y" ]; then
     source sound/sparc/Config.in
  fi

This 'if' statement syntax has *got* to go.  I posted an incomplete
replacement syntax some time ago, but abandoned it because it appeared
Roman was almost ready to merge his new config stuff....

I was aware of this, the only reason why I posted this was to let people
proceed with menuconfig, and to give them a response.

Roman Zippel already posted a correct path, that he also has sent to Linus.
Although I do not understand where the ALSA people are in this game.

The 2.5.39 version of Roman's lkc looked really good IMHO, but I think
more people has to get into the discussion before it will be accepted.
I for one is not the right person to comment on the config
language, old or new.

I'd be happy about a discussion, but if it's not happening soon, it's up
to Linus to accept it.

Thanks, known problem.

Try this patch:
copy-n-pated so may not apply cleanly, try by hand.
