Right, cgo is not run directly.  It is run by the go tool.  It is in effect an
internal program like cc1.

The version suffix should be fine if libexecsubdir in libgo matches
libexecsubdir in gotools, as the go tool will locate cgo via the variable
theGccgoToolDir written to version.go by libgo/Makefile.  I'll see if that
works with --enable-versions-specific-runtime-libs.

The docs are online at http://golang.org/cmd/{go,gofmt,cgo} which is where most
people read them.    The docs come from the program source
(libgo/go/cmd/*/doc.go).  The programs also have -help options.  Would you like
me to add small man pages that direct people to the web pages?
