[Buildroot] SDL_image, SDL_ttf & Co

[julien.boibessot at free.fr]

Hi !

I intend to add SDL_image, SDL_ttf (and probably some other) SDL extentions
support to Buildroot and I'd like to know if the better way is to add these
package generation inside "sdl/sdl.mk" or to create a "package/sdl_xx/"
directory for each package ?
I'm asking that because I want to commit my changes to Buildroot trunk and want
to do it cleanly before submitting you a patch.

Thanks !
Julien
