[at-spi2-core] Build fixes.

[Patrick Welche <pwelche src gnome org>]

commit 377ef7c311a5a3b1718bf4474612c5a47db11fd0
Author: Patrick Welche <prlw1 cam ac uk>

    Build fixes.
    
    - atspi-application.h makes use of DBusConnection* .
    - -Werror-implicit-function-declaration doesn't contain an equal sign in
      my copy of gcc, and is gcc specific.
    - The default behaviour of AC_CHECK_LIB glib-2.0 is to add -lglib-2.0 to
      LIBS which can then cause the search for a dlopen function to fail
      because the flags to find libglib aren't included. Solution is to
      tell AC_CHECK_LIB to do nothing(!)
