init.lxc.static is run in arbitrary containers where the libasan library lxc has been built with isn't always installed. To make it work let's override GCC's default and link both libasan and libubsan statically. It should help to fix issues like ``` ++ lxc-execute -n c1 -- sudo -u ubuntu /nnptest lxc-init: error while loading shared libraries: libasan.so.5: cannot open shared object file: No such file or directory ``` Signed-off-by: -
