And in fact the patch below shows that $(BUILT_SOURCES), which is what
the install target tries to install, contains _generated/errors.py twice.
To test it, apply the patch, build the package with "dpkg-buildpackage -A"
and then try:
make -C src show_BUILT_SOURCES | grep --color _generated/errors.py
You should see _generated/errors.py twice, one because it's listed
explicitly and another one as the result of the patsubst in spec_files.
The question, then, is not why it fails, but why it does not always fail.
Please try to explain how the current Makefile tries to avoid the
failure. I guess it relies on wildcard $(spec_dir)/*.xml having
a particular order, but the order of such wildcard expansion
depends on filesystem ordering, so it may be anything.
So I really think there is a Makefile bug here, even if can't
explain it in full. please forward the bug upstream.
