Afaict this is supposed to at least compile. I currently run into this issue while building (not in tree) openmw. I have no issues with media-libs/libsdl2-2.0.1-r1[-directfb]. There does not seem to be anything depending on libsdl2[directfb] in the tree, so masking the use flag should not cause issues. Even Debian disable directfb for libsdl2 since june 2013: http://anonscm.debian.org/gitweb/?p=pkg-sdl/packages/libsdl2.git;a=blob;f=debian/rules + * Disable directfb backend for now as it's broken and upstream + disables it by default.

They are randomly hacking their way through the day.
if sdl upstream doesn't respond within the next couple of months we will probably drop directfb support from libsdl2
+ 05 Apr 2014; Julian Ospald <hasufell@gentoo.org> libsdl2-2.0.1-r1.ebuild, + libsdl2-2.0.2.ebuild: + remove directfb video support
