using build artifacts with autopkgtest

[Lorenzo <plorenzo@disroot.org>]

Hello Mentors,

I want to add the upstream testsuite of a package that I maintain
(socklog) to autopkgtest. However, when I do so, the test fails
because it uses two tiny C build artifacts (~40KiB) that are build only
to be used in the testsuite and are not part of the deb package.

Is there a way to access the uncleaned build tree from autopkgtest?

If not, I thought to add the two artifacts to the socklog.deb package,
but is there an appropriate path for it?
maybe /usr/lib/socklog/test/ ?
