eglibc 2.16 has removed gets so we need to check for it
being there before using it.


From glibc stdio.h

The function has been officially removed in ISO C11.  This opportunity
   is used to also remove it from the GNU feature list.  It is now only
   available when explicitly using an old ISO C, Unix, or POSIX standard.
