CL 582076 made the GOROOT_BOOTSTRAP set to "", which in turn
causes the next iteration to return true. "$GOROOT_BOOTSTRAP/bin/go"
becomes "/bin/go", which always exists.
Fixes #67654

# GOHOSTARCH: The architecture for host tools (compilers and

|
# system, so the only common reason to set this is to set
|
|
# GOHOSTARCH=386 on an amd64 machine.

|

# GOARCH: The target architecture for installed packages and tools.

# GO_GCFLAGS: Additional go tool compile arguments to use when

|
# building the packages and commands.

|
|
# GO_LDFLAGS: Additional go tool link arguments to use when
|
|
# building the commands.
|
|
#
|
|
# CGO_ENABLED: Controls cgo usage during the build. Set it to 1
|
|
# to include all cgo related files, .c and .go file with "cgo"
|
|
# build directive, in the build. Set it to 0 to ignore them.
