>Mesa provides the flexibility of building without the

>    loader: introduce the loader util lib
>
>By isolating libdrm code by #ifndef __NOT_HAVE_DRM_H we
>can have libdrm-less builds on across all build systems.
>
>This patch converts Android's _EGL_NO_DRM to __NOT_HAVE_DRM_H
>to provide consistency with the other cases within mesa, allows
>compilation of libloader on scons and conditionally links
>against libdrm if present under automake.
