[PATCH 2/3] menuconfig: Add CONFIG_BUILD_DOCUMENTATION

[David Adair]

This provides a way to override the ccache ENABLE_DOCUMENTATION=OFF
setting and restore previous behavior.  It is optional since the
default required to disable the doc build (and avoid the non-ascii
character build failures) is !="y".

It could potentially be useful:
 - If we want the default to be "y"
 - To supress docs on other packages. Would be most useful for the
   autoconf based tools but I could not figure out an easy way to
   accomplish that.
