So this option overrides whatever you have selected above?

 Yann> +	  If you say 'y' here (the default), then all firmware files will
 Yann> +	  be installed, so you can later switch to an alternate firmware.
 Yann> +	  The firmware files will be installed thusly:
 Yann> +	    - the 'default'  will be denoted with '_default' in filenames

That seems different from above where the default version doesn't have
any suffix?

Do we really need this? Can't people just delete the files they don't
want in a post build script like for everything else?
