Description of problem:
If I submit a new build with multiple SRPMs where there is a build dependency between two (or some) of them, Copr should build these in the correct order.
Version-Release number of selected component (if applicable):
Whatever is currently on https://copr.fedoraproject.org
Steps to Reproduce:
1. Create two SRPMs, foo and bar where foo takes longer to build than bar (to prevent racing from hiding the bug) and where bar has a BuildRequires on [the version of] the foo package.
2. Submit them both to Copr in a single build
foo and bar will be built at the same time and bar will fail to build
foo should complete it's build before bar is started because bar depends on something in foo
An existing example of this is building evolution and evolution-ews. The latter will typically fail because it depends on the same version of the former.
