Reviewed-on: https://go-review.googlesource.com/c/158019 gotools/: * Makefile.am (go_cmd_vet_files): Update for Go1.12beta2 release. (GOTOOLS_TEST_TIMEOUT): Increase to 600. (check-runtime): Export LD_LIBRARY_PATH before computing GOARCH and GOOS. (check-vet): Copy golang.org/x/tools into check-vet-dir. * Makefile.in: Regenerate. gcc/testsuite/: * go.go-torture/execute/names-1.go: Stop using debug/xcoff, which is no longer externally visible.
