The standard build assumes the variable is unset.
Make it so, like we do for GOFLAGS, GOBIN, and so on.

People sometimes want to turn on a particular go command flag by default.
In Go 1.11 we have at least two different cases where users may need this.
1. Linking can be noticeably slower on underpowered systems
due to DWARF, and users may want to set -ldflags=-w by default.
2. For modules, some users or CI systems will want vendoring always,
so they want -getmode=vendor (soon to be -mod=vendor) by default.
This CL generalizes the problem to “set default flags for the go command.”
$GOFLAGS can be a space-separated list of flag settings, but each
space-separated entry in the list must be a standalone flag.
That is, you must do 'GOFLAGS=-ldflags=-w' not 'GOFLAGS=-ldflags -w'.
The latter would mean to pass -w to go commands that understand it
(if any do; if not, it's an error to mention it).
For #26074.
For #26318.
Fixes#26585.

I'm tired of having to remember it on every command.
Rebuilding everything is the wrong default.
This CL updates the build script, but the builders may
(or may not) need work, depending on whether they
rebuild using the test command (I doubt it).

The timeouts were increased in CL 2462 and CL 2510
to work around a slowness issue when running Go
programs on a Plan 9 machine on GCE.
Since we figured out this issue, we can restore
the timeouts to their original values.

The wildcard 'std' is defined in documentation to be all the packages
in the Go standard library. It has also historically matched commands
in the main repo, but as we implement core commands in Go, that
becomes problematic. We need a wildcard that means just the library,
and since 'std' is already documented to have that definition, make it so.
Add a new wildcard 'cmd' for the commands in the main repo ($GOROOT).
Commands that want both can say 'std cmd' (or 'cmd std') to get the
effect of the old 'std'.
Update make.bash etc to say both std and cmd most of the time.
Exception: in race.bash, do not install race-enabled versions of
the actual commands. This avoids trying to write binaries while
using them, but more importantly it avoids enabling the race
detector and its associated memory overhead for the already
memory-hungry compilers.

$GOTESTONLY controls which set of tests gets run. Only "std" is
supported. This should bring the time of plan9 builder down
from 90 minutes to a maybe 10-15 minutes when running on GCE.
(Plan 9 has performance problems when running on GCE, and/or with the
os/exec package)
This is a temporary workaround for one builder. The other Plan 9
builders will continue to do full builds. The plan9 buidler will be
renamed plan9-386-gcepartial or something to indicate it's not running
the 'test/*' directory, or API tests. Go on Plan 9 has bigger problems
for now. This lets us get trybots going sooner including Plan 9,
without waiting 90+ minutes.
