In my limited experience, CONFIG_SHELL looks required (or becomes required?).
Without it I encountered the configuration error like:
gcc-base/libstdc++-v3/configure[22664]: syntax error at line 47774 : `;' unexpected
gcc-base/libstdc++-v3/configure[22664]: syntax error at line 17 : `)' unexpected
which bothered me for a while before.
