OK, I understand.

So I will provide the patch with BR2_PACKAGE_DIRECTFB_DEBUG_SUPPORT as 
suggested by Arnout.
Since BR2_PACKAGE_DIRECTFB_DEBUG is still present, I will make it depend 
on BR2_PACKAGE_DIRECTFB_DEBUG_SUPPORT (default yes). 
(--disable-debug-support is ignored if --enable-debug is set.)
Of course it is still possible to remove BR2_PACKAGE_DIRECTFB_DEBUG 
later...
