Fix invalid memory access in do_lookup_x.

[BZ #13579] Do not free l_initfini and allow it to be reused
on subsequent dl_open calls for the same library. This fixes
the invalid memory access in do_lookup_x when the previously
free'd l_initfini was accessed through l_searchlist when a
library had been opened for the second time.

[PATCH] Make sunrpc code usable again

New configure option --enable-obsolete-rpc makes the deprecated RPC
headers and functions available at compile time as they were before
version 2.14.  This option will be removed at some time in the future
after the TI-RPC library becomes fully sufficient for the needs of
existing applications.
