It's been deprecated for three ages and two forevers, so it's not surprising
it's not compiled in.

Recompile with CONFIG_IKCONFIG_PROC.  This is not done in Debian's kernels
as using packages means the text file won't come out of sync with its kernel
(both are versioned); they're in the same directory so even fancy mounts
won't put them apart.  Using a text file is better than /proc as you can
obtain the config of a non-running kernel.
