   Avoid parse time errors due to dependency on x11, for distros without x11
        
   BitBake raises some errors when processing recipes that depend on x11
   for distros that don't have x11 in DISTRO_FEATURES. To work around
   that issue, REQUIRED_DISTRO_FEATURES = "x11" (from
   distro_features_check.bbclass) has been set for the following recipes:
                            
    * cacao
    * classpath
    * jamvm
    * openjdk-6-release
    * openjdk-7-release
                                                   
 That makes BitBake skip those recipes during the cache generation
 (they'd still be parsed, but ignored).

Even if we revert this commit, the openjdk-7-jre build will fail 
due to dependency on gtk+, libxt...etc. 

Recently Jens Rehsack did some work in this direction for icedtea7:
http://lists.openembedded.org/pipermail/openembedded-devel/2015-October/103849.html

We will have to follow that way to get rid of the x11 dependency in other packages.
