After the development it is disabled (changed to a name that

register ABI for ARM64 and PPC64, I don't think the magic names
were used. I think they can now be removed.

In the beginning the Go compiler was in C, and C had a function
'getgoroot' that returned GOROOT from either the environment or a
generated constant. 'getgoroot' was mechanically converted to Go
(as obj.Getgoroot) in CL 3046.
obj.Getgoroot begat obj.GOROOT. obj.GOROOT begat objabi.GOROOT,
which begat buildcfg.GOROOT.
As far as I can tell, today's buildcfg.GOROOT is functionally
identical to runtime.GOROOT(). Let's reduce some complexity by
defining it in those terms.
While we're thinking about buildcfg.GOROOT, also check whether it is
non-empty: if the toolchain is built with -trimpath, the value of
GOROOT might not be valid or meaningful if the user invokes
cmd/compile or cmd/link directly, or via a build tool other than
cmd/go that doesn't care as much about GOROOT. (As of CL 390024,
runtime.GOROOT will return the empty string instead of a bogus one
when built with -trimpath.)

Invoking a VCS tool requires that the VCS tool be installed, and also
adds latency to build commands. Unfortunately, we had been mistakenly
loading VCS metadata for tests of "main" packages.
Users almost never care about versioning for test binaries, because
'go test' runs the test in the source tree and test binaries are only
rarely used outside of 'go test'. So the user already knows exactly
which version the test is built against, because the source code is
right there — it's not worth the overhead to stamp.

However, the test for the package expects zoneinfo.zip to definitely
