All these build errors have already been addressed. In case you don't
want to wait until the final release you can rebuild the SDK yourself
with the following steps:
 $ git clone git://anongit.freedesktop.org/gstreamer-sdk/cerbero; cd cerbero
 $ ./cerbero-uninstalled -c config/cross-android.cbc bootstrap
 $ ./cerbero-uninstalled -c config/cross-android.cbc package gstreamer-sdk

For this first preview release we only provided the static libraries
that are used for the ndk-build integration, as it's the only thing
you really need in the applications' development. But for testing
purpose, we will also provide a tarball with the shared libraries and
GStreamer tools that you could use to test pipelines in the device. If
you try to compile the SDK yourself, you will see that 2 tarballs are
created, the last one with the "-runtime" suffix contains what you are
looking for.
