Ubuntu. :)

According to our experience and Google
(https://launchpad.net/ubuntu/+source/iptables/+bug/66681), this can be
solved using the -fno-stack-protector option in CFLAGS and CXXFLAGS.
However, our build system already sets this variable for you. Can you
please perform "make cleanall && make V=1" in l4/pkg/ipcmon/server/src, and
check if the output contains the -fno-stack-protector option?
