elflink: Allocate space for 'realname'

search_dirs() expects the 'realname' argument to point to space
allocated for storing the real path name. Currently we're passing an
uninitialized pointer which was highlighted by the following build
warning,

elflink/load_env32.c:155:18: warning: ‘realname’ may be used uninitialized in this function
