cmd/pack: broken on Windows, cannot find GOCHAR in 'go env' output

[bradfitz]

cmd/pack is now broken on Windows:

--- FAIL: TestHello (0.02 seconds)
    pack_test.go:198: cannot find GOCHAR in 'go env' output
FAIL
FAIL    cmd/pack    0.063s

e.g. http://build.golang.org/log/500ac7db7b9db0643d2a594d8ca4d8bac32facdc

as of
https://code.google.com/p/go/source/detail?r=48a4a9afb88b894eb2510469587f1e832185cea6

Probably can't find go.
