glib2: fix missing gobject library when linking glib-compile-resources (#826)

The automake template does not specify libgobject-2.0.la as _LDADD dependency
for glib-compile-resources, leading to the following linker error:

  .../ld: warning: libgmodule-2.0.so.0, needed by ./.libs/libgio-2.0.so, not found (try using -rpath or -rpath-link)
  ./.libs/libgio-2.0.so: undefined reference to `g_module_supported'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_symbol'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_close'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_error'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_open'
  collect2: error: ld returned 1 exit status

This commit introduces a patch to add the missing libtool archive to the list
of libraries to link.

Due to the update of the .am file, a full autoreconf is required to update
configure and Makefile, leading to the following error:

  error: HAVE_GTK_DOC does not appear in AM_CONDITIONAL

Therfore another patch is added to properly fix the conditional when using
automake-1.15.

Finally extend the copyright year in the Makefile and enable the generic
autoreconf fixup to properly build and link glib2.
