Hi Felix,

This patch set itself is fine. But when testing it with "More build
time reductions", there are some issues.

On fast testsuite, CompatTest.test_compat_recipe fails with:
ERROR: mc:qemuarm64-trixie:libhello-compat-0.3-f4a5669-r0 do_dpkg_build:

1, None, None)

It attempted to find the changelog directly under build/debian, it's 
definitely not right.

But running CompatTest.test_compat_recipe alone passes. In the fast suite,
DevTest and LocaleTest run before CompatTest, so one of the earlier builds
probably affects it. I’ve been trying to find which target affects it, but
haven’t found it yet.
