[PATCH] Update build instructions - don't need Gallium EGL driver anymore

Sun Feb 13 17:13:21 PST 2011

The mess of mesa build flags had been due to the Gallium EGL driver not
working with Intel, while being required by Nouveau.  Thanks to Dave
Airlie, as of today, Nouveau no-longer requires Gallium EGL and can use
DRI2 EGL.  ATI/AMD has been able to for a while.  So we should be able
to substantially simplify the mesa build flags.

Build flags removed:
--engable-egl - default
--with-state-trackers=glx,dri,egl - dri,xorg,egl is default, glx not needed
--with-egl-platforms=drm - included in default
--enable-gles-overlay - adds --enable-gles1, not needed
--with-dri-drivers=i915,i965 - included in default
--disable-gallium-{i915,i965} - covered by --disable-gallium-egl
