commit d5a770f2c139a335e7602bec60dbeabd4add1e8b

    scripts: only generate config from feature flag if fully match
    
    Without this change the code checked if the string was contained in the
    feature option and not if the string matches the complete word. This only
    removes the nand option from the omap24xx target, the other changes are
    only removing options which were added twice.
