[almighty] Makefile error and Jenkins naster build

[Baiju Muthukadan]

Hi Konrad,

There was an error in the "make generate" during this master build:
https://ci.centos.org/view/Devtools/job/devtools-almighty-core-build-master/44/console

You can see these lines there:
-----------------------------------------------------------
+ make docker-generate
docker exec -t -i "almighty-core-local-build" make generate
cd vendor/github.com/goadesign/goa/goagen && go build -v
[...snip...]
PATH="$(PATH):vendor/github.com/jteeuwen/go-bindata/go-bindata"
vendor/github.com/elazarl/go-bindata-assetfs/go-bindata-assetfs/go-bindata-assetfs
-debug assets/...

/bin/sh: PATH: command not found
-----------------------------------------------------------

But it never made the build to fail and prevented Jenkins to deploy
the artifact. We have fixed this issue here:
https://github.com/almighty/almighty-core/pull/286 I had a look at all
the make files to see any potential similar issue, but I couldn't find
anything. Do you think we need to anything else in Jenkins to capture
these kind of issues? May be use some Jenkins plugin to search for
"command not found" string and make Jenkins to fail?

Regards,
Baiju M
