So I think we should switch to using go1.4, shouldn't we? Or is there anything that I may be missing?

If we do that, we will have to submit go1.4 to Leap and Factory.

I did that and for Factory the build fails :(

Seems it is a somehow "known" bug with binutils 2.27

https://github.com/golang/go/issues/16906

The error is

    cannot load DWARF output from $WORK/os/user/_obj//_cgo_.o: decoding dwarf section info at offset 0x4:    unsupported version 0

I am considering if we should get back to build go with gcc-go or try to fix binutils (or open a bugzilla entry)

Any thoughts?
