When USE="sdl" is enabled for media-libs/gegl (tested on version 0.4.36-r1), the ebuild configures the package to enable sdl1, even though sdl2 support is available. After modifying the ebuild to enable sdl2 support instead, I was still able to compile gegl without issues. Other distributions (checked with Clear Linux and Arch) build gegl with sdl2 support as well. Unless there are any reasons not to, I'd suggest for Gentoo to do the same.
Sorry for delay. I wanted to add new USE flag on version bump. The meson.build script allows to turn on/off sdl1 and sdl2 support simultaneously or independent. Therefore it will be possible to switch of sdl1 support in media-libs/gegl-0.4.38 package.
