[Buildroot] [PATCH 1/3] package/sdl2: be more explicit in disabling optional features

[Thomas Petazzoni via buildroot]

Add many more explicit --disable-<foo>, as we have for example seen
video-vivante being autodetected when not needed.

[Buildroot] [PATCH 2/3] package/sdl2: be explicit about OpenGL ES options

[Thomas Petazzoni via buildroot]

In addition to --enable-video-opengles, SDL2 configure script also
looks at --enable-video-opengles1 and --enable-video-opengles2. Since
all OpenGL ES providers in Buildroot provide at least up to OpenGL ES
2, enable both options when BR2_PACKAGE_SDL2_OPENGLES=y.

[Buildroot] [PATCH 3/3] package/sdl2: rework KMS/DRM video driver dependencies

[Thomas Petazzoni via buildroot]

The KMS/DRM video driver of SDL2 can currently only be enabled when
mesa3d is the OpenGL provider, as the option has a dependency on
BR2_PACKAGE_MESA3D_GBM. Now that we have a libgbm virtual package and
BR2_PACKAGE_HAS_LIBGBM, we can do better.

However, this has uncovered a number of additional related issues that
are resolved at the same time. Here are some details:

 * the 'depends on BR2_PACKAGE_LIBDRM' is changed to a select, as we
   normally do for library dependencies. Due to this, we inherit a
   BR2_TOOLCHAIN_HAS_THREADS dependency.

 * the 'depends on BR2_PACKAGE_MESA3D_GBM' is changed to 'depends on
   BR2_PACKAGE_HAS_LIBGBM', and the 'mesa3d' dependency is changed to
   'libgbm'.

 * the KMS/DRM video driver in SDL2 needs EGL (hence the additional
   'depends on BR2_PACKAGE_HAS_LIBEGL' and the libegbl dependency is
   added in the .mk file). But in turn, EGL support is only checked
   when either OpenGL or OpenGLES support is enabled in SDL2, which is
   why we add logic to select the appropriate options.

I think this is a feature change, so this does not fit master. However,
it can't be applied to next either as it requires the previous tw
patches.

Do, I've left this pending for later (either after we merge next back
into master, or after we merge the next -rc into next).
