In configure.ac:

# If we don't have the X11 platform, set this define so we don't try to
include
# the X11 headers.
if ! echo "$egl_platforms" | grep -q 'x11'; then
    DEFINES="$DEFINES -DMESA_EGL_NO_X11_HEADERS"
    GL_PC_CFLAGS="$GL_PC_CFLAGS -DMESA_EGL_NO_X11_HEADERS"
fi

The MESA_EGL_NO_X11_HEADERS is only specifying whether or not EGL has the
x11 platform.  It's unrelated to GLX.  You can build with EGL and no x11
platform but still have GLX.  What about adding 2 -D defines in configure.ac
for MESA_HAVE_GLX and MESA_HAVE_EGL ?
