What did you do?
I ran make for https://github.com/glycerine/vhaline Makefile does go install on the library github.com/glycerine/vhaline/vhaline and then on a test executable; github.com/glycerine/vhaline/cmd/vhaline
What did you expect to see?
successful build. build is successful without CGO_ENABLED=0
What did you see instead?
[jaten@biggie vhaline]$ make
cd vhaline && go install && cd ../cmd/vhaline && go install
go install net: open /usr/local/go/pkg/linux_amd64/net.a: permission denied ### problem!

Work on better caching will fix this. I have a prototype. Not for Go 1.9 but probably for Go 1.10.
That would be wonderful if that was the outcome of this ticket, the “official binary + cross compile + go install” story is the last remaining hurdle to Go developers having a seamless cross compilation experience with our official builds.
