Two packages cannot provide /usr/bin/go. The update-alternatives
mechanism is a solution to that (no package provide /usr/bin/go, but
they register to update-alternatives that will setup the link). However,
it doesn't work well for compilers as it would result in
environment-dependent build.

The situation is exactly the same with gcc. You install gcc, you get
/usr/bin/gcc which is a symlink to gcc-6. You install gcc-6, you get

Install golang-1.7-go, not golang-1.7. golang-1.7 is specifically here
to also install the documentation.
Test programs at their boundary values.
