Subject: Travis: When testing installation, build in separate dir, otherwise
 in checkout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The rationale is that installation from a tarball is a common task
that everyone performs.  For all other builds, we do specialised
tests, and might as well build them directly in the checkout, which
also gives us fuzz corpora.
