Bug#779542: st: Please add sh4 support
st currently fails to build from source since it doesn't recognize Debian's
sh4 (SuperH) port as a host architecture. It would be nice if support for
sh4 could be added to the liburcu package unless there is a particular
reason why it should not support this architecture.
The error message during a failed build attempt  is:
if [ ! -d LINUX_3.2.44-00829-g14e6110_OPT ]; then mkdir LINUX_3.2.44-00829-g14e6110_OPT; fi
