I haven't found any normal distro not having config in place (openSUSE/SLE, Debian/Ubuntu,
CentOS/Red Hat), but there might be some. I guess most of embedded devices don't have
that (it's a question if they have IKCONFIG_PROC=y) but why not to try it.

I wonder if we'd benefit from having these functions in shell API:
is_enabled(CONFIG_FOO)
is_module(CONFIG_FOO)
is_builtin(CONFIG_FOO)

which would do simple grep of either /boot/config-$(uname -r) or /proc/config.gz.

The first three are inspired with kernel macros from include/linux/kconfig.h
