Assuming that you are compiling with GCC v5.x, this issue is easily
reproducible. 'Undefined symbol' is very possible to happen for other
inline routines too. To confirm this I changed inline to static inline
and re-compiled and failed to start with another routine(gf_sql_str2jm)
undefined.

I don't know why we don't hit this issue while glusterfs is being
compiled without debug mode.
