libEGL was incorrectly exporting *all* symbols, public and private.
This patch adds -fvisibility=hidden to libEGL's linker flags to ensure
that only symbols annotated with __attribute__((visibility("default")))
get exported.
Sanity-checked with libEGL's builtin DRI2 driver and the i965 DRI driver
by running Piglit on X/EGL and by running weston-gears on Weston as an
X client.
Sanity-checked with libEGL's Gallium driver (which is not built-in) and
the swrast Gallium driver by running es2gears_x11.
Kristian reviewed the symbol diff in `nm libEGL.so`.
