./make.bash ubuntu-> windows的Go lang安装问题

Question

I have tried to search and found a lot of topics which are related to my problem, but none of them I could follow to success. I can go run and go get with no issues, but I need to compile into windows and there I have problems please see bellow

mikhail@mikhail-desktop:/usr/lib/go/src$ sudo ./make.bash 
# Building C bootstrap tool.
cmd/dist
go tool dist: $GOROOT is not set correctly or not exported
    GOROOT=/usr/share/go
    /usr/share/go/include/u.h does not exist
mikhail@mikhail-desktop:/usr/lib/go/src$ go env
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/mikhail/Documents/FL/0go"
GORACE=""
GOROOT="/usr/lib/go"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
TERM="dumb"
CC="gcc"
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"
CXX="g++"
CGO_ENABLED="1"
mikhail@mikhail-desktop:/usr/lib/go/src$ 

By some reasons it thinks the GOROOT is /usr/share/go while it actually /usr/lib/go

I think it somehow connected to Debian/Ubuntu thing. I seen such issues but related to 0.9. version.

I have installed go from source into ~/go and then everything went quite OK, now I can compile to windows from ubuntu with help Introduction to cross compilation with go and LiteIDE.
