 The build flags are shared by the build and test commands:
 
-	-a
-		force rebuilding of packages that are already up-to-date.
-	-n
-		print the commands but do not run them.
-	-p n
-		the number of builds that can be run in parallel.
-		The default is the number of CPUs available.
-	-race
-		enable data race detection.
-		Supported only on linux/amd64, darwin/amd64 and windows/amd64.
 	-v
 		print the names of packages as they are compiled.
-	-work
+	-r
-		print the name of the temporary work directory and
+		run program after built.
-		do not delete it when exiting.
-	-x
-		print the commands.

-	-ccflags 'arg list'
-		arguments to pass on each 5c, 6c, or 8c compiler invocation.
-	-compiler name
-		name of compiler to use, as in runtime.Compiler (gccgo or gc).
-	-gccgoflags 'arg list'
-		arguments to pass on each gccgo compiler/linker invocation.
-	-gcflags 'arg list'
-		arguments to pass on each 5g, 6g, or 8g compiler invocation.
-	-installsuffix suffix
-		a suffix to use in the name of the package installation directory,
