# History: The configure script used to reject the shared flag on the generic target.
# This meant that we needed to fall back to manual shared lib creation.
# However, the modern configure script permits the shared flag and assumes ELF.
# Additionally, the libvpx.ver would need to be updated to work properly.
# As a result, we disable this universally, but keep it around in case we ever need to support
# something "special".
