Version details: 0.8.11

On Cygwin (and MinGW), shared libraries and modules must have all symbols
resolved at link time.  This involves passing "-no-undefined" to libtool via
*_la_LDFLAGS and all required link libs in *_la_LIBADD.

I'm attaching a patch which fixes these issues on Cygwin with gstreamer-0.8.11.

* configure.ac:
  add -no-undefined to GST_LIB_LDFLAGS and GST_PLUGIN_LDFLAGS;
  add GST_LIB_LIBS to GST_OBJ_LIBS.

* gst/Makefile.am:
  add -no-undefined to libgstreamer_ at GST_MAJORMINOR@_la_LDFLAGS

* gst/elements/gstmultifilesrc.c:
  Cygwin (as of 1.5.18) does not provide madvise

* libs/gst/bytestream/Makefile.am:
  correct definition of libgstbytestream_la_LIBADD

There is one additional issue, that the getbits-i386 code doesn't compile on
Cygwin.  Perhaps the best way to work around this is not to define HAVE_CPU_I386
if $target_os = cygwin.
