commit 5f03ce1213782c9ddb9bb010dac127bb554092cc

    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.
