Bring back the test-suite export in test-release without bringing back the build failures.

[dsanders]

Summary

r257791 disabled the test-suite export since the addition of CMakeLists.txt was
causing build failures. This patch exports the test-suite again but does so
outside the source tree so that it isn't included in the Phase[123] builds.

lgtm, thanks!

The code will become simpler when we rip out all the autoconf code, but I'm holding off on that until after the release to make merges easier.

Thanks. Committed to branch in r259093 and trunk in r259094. (I forgot I was on the branch and committed there first).
