Fix PR lto/49664: liblto_plugin.so exports too many symbols
So right now liblto_plugin.so exports many libiberty symbols and
simple_object file symbols but really it just needs to export onload.
This fixes the problem by using "-export-symbols-regex onload" on
the libtool link line.
lto-plugin/ChangeLog:
PR lto/49664
* Makefile.am: Export only onload.
* Makefile.in: Regenerate.
