The linker attempts to resolve this undefined symbol at link time, causing the test to fail with: undefined reference to `THIS_SYMBOL_SHOULD_BE_UNDEFINED' The test is designed to verify garbage collection behavior of #[no_mangle] functions and used(compiler)] statics. This appears to be a PowerPC-specific linker behavior issue. Temporarily disable this test on PowerPC until the underlying issue is resolved upstream.
