 > However, because BR2_STATIC_LIBS belongs to a choice, when
 > BR2_PREFER_STATIC_LIB is selected, it does not affect the choice.
 > So, existing Buildroot configurations, which have BR2_PREFER_STATIC_LIB
 > set, will silently end with BR2_SHARED_LIBS ("shared only") enabled.

 > So, the backward compatibility is not kept.

 > Besides, the legacy BR2_PREFER_STATIC_LIB option does not select
 > BR2_LEGACY, so the user is not notified of this legacy option, and the
 > build silently continues with some undesired changes.

 > This patch removes the inefficient BR2_STATIC_LIBS selection, correctly
 > selects the BR2_LEGACY option and extend the help message so the user
 > can easily know how to update his/her Buildroot configuration.
