First of all, a defconfig file (which you create by running 'make
savedefconfig')  is quite a bit easier to read than the very verbose
.config.


Secondly, I see you have both directfb and X11:

BR2_PACKAGE_DIRECTFB=y
BR2_PACKAGE_DIRECTFB_TRACE=y
BR2_PACKAGE_DIRECTFB_XSERVER=y
BR2_PACKAGE_XORG7=y
BR2_PACKAGE_XSERVER_XORG_SERVER=y

You can most likely drop directfb. SDL is also relatively big. You also
have a number of unneeded X libraries.
