When building the gold testsuite with LDFLAGS="-Wl,--as-needed", the following tests fail due to undefined symbols:

FAIL: exception_separate_shared_12_test (exit: 127)
===================================================

./exception_separate_shared_12_test: symbol lookup error: ./exception_shared_1.so: undefined symbol: _Z2f1v
