In fact, I'd forgotten I'd had an exchange with a Go developer (I wish
I could remember who) precisely over that "bootstrap" issue. Go1.4.3
needs a small enhancement, I forget from which target onwards because
of some executable binary improvement even for Linux. But the
bootstrap version is the recommended one, recently, as I mentioned.

Here is Brad's message:

You'll want to use the release-branch.go1.4 branch, not Go 1.4.3.

See https://golang.org/doc/install/source#go14 which says:

> To build a bootstrap toolchain from source, use either the git branch release-branch.go1.4 or go1.4-bootstrap-20171003.tar.gz, which contains the Go 1.4 source code plus accumulated fixes to keep the tools running on newer operating systems. (Go 1.4 was the last distribution in which the toolchain was written in C.) After unpacking the Go 1.4 source, cd to the src subdirectory, set CGO_ENABLED=0 in the environment, and run make.bash (or, on Windows, make.bat).
