patch

Recent EGL headers on Linux use EGL_NO_X11 instead of MESA_EGL_NO_X11_HEADERS on systems where X11 should not be used. As a result, on systems where X11 is not present, the configure script would fail to enable EGL (and Wayland) support.

The attached patch should fix this issue. The old MESA_EGL_NO_X11_HEADERS remains for systems that do not have the updated headers. Note that the newer macro has already been added to EXTRA_CFLAGS, so the build still worked, it is just the detection during configuration that is failing.
