+# Environment variables that control make.rc:
+#
+# GOROOT_FINAL: The expected final Go root, baked into binaries.
+# The default is the location of the Go tree during the build.
+#
+# GOHOSTARCH: The architecture for host tools (compilers and
+# binaries).  Binaries of this type must be executable on the current
+# system, so the only common reason to set this is to set
+# GOHOSTARCH=386 on an amd64 machine.
+#
+# GOARCH: The target architecture for installed packages and tools.
+#
+# GOOS: The target operating system for installed packages and tools.
+#
+# GO_GCFLAGS: Additional go tool compile arguments to use when
+# building the packages and commands.
+#
+# GO_LDFLAGS: Additional go tool link arguments to use when
+# building the commands.
+#
+# CGO_ENABLED: Controls cgo usage during the build. Set it to 1
+# to include all cgo related files, .c and .go file with "cgo"
+# build directive, in the build. Set it to 0 to ignore them.
