[Docker-maint] Bug#841258: golang: incorrect upgrade from 1.6 to 1.7 when gccgo is also present

[Eric Cooper]

Package: golang
Version: 2:1.7~1
Severity: normal

I had both gccgo and golang installed.  Before the recent upgrade to
golang 1.7, /usr/bin/go was the golang compiler.

After a recent apt-get upgrade, I noticed compilation failures and
found that /usr/bin/go was now gccgo-6, even though golang-1.7 had
been installed.

I had to purge and reinstall golang to fix the problem.
