Installation of Go on ARM v8

Dave,
Is anyway to build the arm5 version of GO 1.7.3 on the same intel host? I tried doing the above steps for ARM5 but unfortunately the build is running out of memory.
I need to build the binary for ARM5 version of GO on some other machine.
I have checked your articles in cross-compilation, but I am not sure if that allows to build the GO installation itself.

Thanks,
Marcelo
