Makefile race condition - repos.mk

[Maxim V. Yefimov]

The error occurs occasionally:

Step to reproduce:

Start the normal custom ISO build from jenkins with the job provided by Mirantis. Makeflags = -j --output-sync

Expected results: Normal build with a new ISO

Actual results:

Error:

Unable to reproduce on our side. Perhaps there is interference with side patches. But fix is obvious.

https://review.openstack.org/#/c/459686/ has been merged.

Anton,

The customer, who hit the issue, believes that the committed fix will make the build system more robust, but will not eliminate the race condition itself. He has proposed another patch: http://paste.openstack.org/show/ZWBOg9Ai0DAWiE1QT18E/

Would you please review the proposed fix above?

I cannot do anything with the commit to the master branch, please cherry-pick the commit to stable/mitaka when it is merged in master.
