The libgo library doesn't provide runtime.SetCgoTraceback, which is used by the gc toolchain to collect combined C/Go tracebacks. Since gccgo uses the normal C ABI, the function is not necessary for gccgo, and it is difficult to implement. This patch changes the runtime tests so that the ones that require SetCgoTraceback are not built for gccgo. Those tests are not built today, but they will be soon. Patch bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed to mainline.
