Handle symbols defined/referenced only within IR
The plugin is called to claim symbols in an archive element from
plugin_object_p. But those symbols aren't needed to create output.
They are defined and referenced only within IR. get_symbols should
return resolution based on IR symbol kinds.
PR ld/20070
* Makefile.am (noinst_LTLIBRARIES): Add libldtestplug4.la.
(libldtestplug4_la_SOURCES): New.
(libldtestplug4_la_CFLAGS): Likewise.
(libldtestplug4_la_LDFLAGS): Likewise.
* Makefile.in: Regenerated.
* plugin.c (get_symbols): Return resolution based on IR symbol
kinds for symbols defined/referenced only within IR.
* testplug4.c: New file.
* ld/testsuite/ld-plugin/pr20070.d: Likewise.
* ld/testsuite/ld-plugin/pr20070a.c: Likewise.
* ld/testsuite/ld-plugin/pr20070b.c: Likewise.
* testsuite/ld-plugin/plugin.exp (plugin4_name): New.
(plugin4_path): Likewise.
Add a test for ld/20070.
