On AIX when external linking, for some symbols we need to add dummy references to prevent the external linker from discarding them. Currently we add the reference unconditionally. But if the symbol doesn't exist, the linking fails in a later stage for generating external relocation of a nonexistent symbol. The symbols are special symbols that almost always exist, except that go:buildid may not exist if the linker is invoked without the -buildid flag. The go command invokes the linker with the flag, so this can only happen with manual linker invocation. Specifically, test/run.go does this in some cases. Fix this by checking the symbol existence before adding the reference. Re-enable tests on AIX. Perhaps the linker should always emit a dummy buildid even if the flag is not set... Fixes #54814.
