>Description:

	The Go compilers appears to have embedded the build-time GOROOT
	directory in it.  It does not exist at run time.

>How-To-Repeat:

	Building Go-based packages fails:

	===> Building for gh-2.58.0
	go: cannot find GOROOT directory: /tmp/kim/pkgsrc/lang/go123/work/go

	Trying to obtain the Go compiler version fails:

	> /usr/pkg/bin/go123 version
	go: cannot find GOROOT directory: /tmp/kim/pkgsrc/lang/go123/work/go

>Fix:
