[gnome-keyring] Put ABI symbol checks into 'make check'

[Stefan Walter <stefw src gnome org>]

commit cae8d5f914579df7e116af0e8f6e969f4253c50c
Author: Stef Walter <stefw collabora co uk>
Date:   Thu Aug 25 11:50:18 2011 +0200

    Put ABI symbol checks into 'make check'
    
     * We have files in which all public symbols for the gck and gcr
       libraries, and then check these against the linked libraries.
     * Not a panacea for ABI changes, but at least a simple check
