Ah.  I should put this in the kernel hacking lessons.

Many distros ship with a complicated web of symbolic links that I
won't go into detail about here.  The bottom line is:

Make sure /usr/src/linux is a symlink to your current build tree, or
the build won't work.

So if you're compiling a kernel in /usr/src/linux-2.4.19, you need to
do:

cd /usr/src/
ln -s linux linux-2.4.19

And then your build will work.
