Bug#779541: liburcu: Please add sh4 support
liburcu currently fails to build from source since it doesn't recognize Debian's
sh4 (SuperH) port as a host architecture. Similar to #776924, 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:
libtool: compile: gcc -DHAVE_CONFIG_H -I. -I./urcu -I./urcu -D_FORTIFY_SOURCE=2 -Wall -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -c wfqueue.c -fPIC -DPIC -o .libs/wfqueue.o
