gold: Properly remove the versioned symbol
When the versioned symbol foo is removed from the shared library, the
".symver foo,foo@VER" directive provides binary compatibility for foo@VER.
In this case, the unversioned symbol foo should be hidden and shouldn't
generate a multiple definition error.
PR gold/31830
* resolve.cc (Symbol_table::resolve): Move symbol version handling
to ...
* symtab.cc (Symbol_table::add_from_object): Here. If the hidden
version from .symver is the same as the default version from the
unversioned symbol, don't make the unversioned symbol the default
versioned
symbol.
* testsuite/Makefile.am (check_SCRIPTS): Add ver_test_pr31830.sh.
(check_DATA): ver_test_pr31830_a.syms and ver_test_pr31830_b.syms.
(ver_test_pr31830_a.syms): New.
(ver_test_pr31830_b.syms): Likewise.
