Looks like your gccgo build is broken. How exactly did you build and install it? Does any program work? What are the contents of the directory /opt/gccgo/lib64/go?

Note that if you had an existing build directory, the libgo Makefile was recently changed, such that you need to remove your existing libgo directory and rebuild, as mentioned at https://groups.google.com/d/msg/gofrontend-dev/20qRNKwJK1M/lHwm5NSwAgAJ .

Here's how I installed gccgo from a fresh debian jesse image on GCE:
Create the machine:

gcloud compute instances create go --machine-type n1-highcpu-32 --boot-disk-size 30GB --boot-disk-type pd-ssd

Build gccgo:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install -y bison build-essential flex git
sudo apt-get purge
mkdir src
cd src
git clone https://github.com/gcc-mirror/gcc.git --depth 1
cd gcc
contrib/download_prerequisites
cd ..
mkdir gcc-build
cd gcc-build
../gcc/configure --prefix=/opt/gccgo --enable-languages=c,c++,go --disable-multilib --with-ld=$(which ld.gold)
make -j24
sudo make install

/opt/gccgo/lib64/go is empty except for /opt/gccgo/lib64/go/7.0.0/x86_64-pc-linux-gnu/, the content of which is:

Oh, and the gcc SHA I built from seems to be more recent than the email you linked:

Does any invocation of the newly installed go tool work to build a program?

Yes, go test without -i works.

Fixed on GCC mainline by SVN revision 239486.

But that fix is not great, because it only works for the gccgo-specific version of the go tool. That version of the go tool has a known list of standard packages that it relies on in various ways. Reopening this issue in order to work out a better fix in the go tool.

@ianlancetaylor ianlancetaylor changed the title from gccgo: `go test -i ./...` fails with `can't load package: ... cannot find package "<stdlib>"` to cmd/go: go test -i -compiler=gccgo does not work if gc standard packages are not installed Aug 15, 2016

cmd/go: ignore errors from go/build for standard packages
    
    The go/build package does not know that gccgo's standard packages don't
    have source, and will report an error saying that it can not find them.
    Work around that in the cmd/go sources, since the go/build sources don't
    currently have a list of standard packages.
    
    This should get a real fix in the master sources, somehow.
    
    Fixes golang/go#16701.
