[lxc-devel] [PATCH] quiet gcc 4.4.7 warning about saveptr use before initialization

The recent change to use strtok_r causes a build warning with this older
gcc version, so initialize saveptr to NULL to quiet the compiler and
unbreak the build. There was no warning with gcc 4.7.2 that I
originally tested with.
