There is a strange bug with Kconfig, maybe you are hitting it. Basically, if a Kconfig symbol does not have a string description attached to it, it is not possible to select it directly. Have a look at all the "kconfig hacks" patches that are here as workaround, for instance: https://git.lede-project.org/?p=source.git;a=blob;f=target/linux/generic/patches-4.4/254-textsearch_kconfig_hacks.patch;hb=HEAD I tried to track the bug down, but it's quite complex. It definitely looks like it comes from the scripts/kconfig tool upstream, not from OpenWRT/LEDE. OpenWRT/LEDE passes all the kernel symbols it wants to select to scripts/kconfig from Linux, presumably to handle symbol dependencies in the kernel. But kconfig seems to ignore symbols for which there is no string description (in the KConfig file that defines the symbol).
