The runtime/internal/startlinetest package contains a call to a function defined in runtime_test. Generally this is fine as this package is only linked in for runtime_test. Except that for "go install -buildmode=shared std", which include all packages in std, including this test-only internal package. In this mode, the caller is included in the linking but the callee is not, causing linking error. Work around it by calling runtime_test.callerStartLine via a function pointer. The function pointer is only set in runtime_test. In the shared std build, the function pointer will not be set, and this is fine. Fixes #57334.
