[pkg-go] Bug#887983: [patch] fix usage on powerpc

[Michael Vogt]

package: golang-github-boltdb-bolt
version: 1.3.1-1

Dear golang-github-boltdb-bolt maintainers,

attached is a debdiff with a fix to make packages that use boltdb work
on powerpc. The build currently fails because the "brokenUnaligned" is
not defined on powerpc.

I submited this fix upstream to
https://github.com/boltdb/bolt/pull/740 however upstream does not
accept PRs anymore (even for trivial fixes like this :(

I also send the fix to the coreos fork of bolt
(https://github.com/coreos/bbolt/pull/73) where it was accepted right
away.

Cheers,
 Michael
