If more +than one set of flags is passed, the last set is passed to the external linker, +and the rest are silently ignored. + +`go_binary` and `go_test` should look for -extldflags in gc_linkopts and +combine the flags into a single list passed to `go tool link`. This includes +flags generated by the rules themselves. + +This test checks this behavior by adding extra rpaths, which has an observable +effect on a `go_binary` linked with the external linker. The shell script checks +that these paths are present. |
