Add -Bsymbolic configure check

gst-libav doesn't link on FreeBSD with either clang or gcc.

libav is build with -Bsymbolic. The solution we can up with was to build all
parts with -Bsymbolic (-Bsymbolic-functions is not sufficient) so teach the
gstreamer part to build with -Bsymbolic too.

Both parts are build with -DPIC and -fPIC, so that is not it.
