* The SRC_URI is not accessible.
So need to add mirror site referred by the original site.
* The problem is that
http://download.savannah.gnu.org/releases redirects to closest mirror
and few mirrors (e.g. .jp) weren't working correctly while
http://download-mirror.savannah.gnu.org/releases/ seems to be reliable.
* Add SAVANNAH_GNU_MIRROR and SAVANNAH_NONGNU_MIRROR variable in bitbake.conf.
* Change the SRC_URI using the new variable.
