[Buildroot] [PATCH 1/1] package/sunxi-mali: allow EGL type = X11

[Iñigo Huguet]

This patch allow to use sunxi-mali for OpenGLES acceleration for
apps running on top of X11 with EGL interface.

For example, QT Quick 2 apps have to use GLX or EGL to run in an
X server, but GLX is not always available, specially in OpenGLES
only capable systems, like the ones with GPU Mali.
