With a bit more information to skip more error patterns, I actually
got an unpatched HEAD build able to work properly as well, with:
ignore_errors=inconsistent,gcov,range,empty,usage,usage,empty,empty,path

The VPATH build is indeed looking pretty broken here, with the
top-level including the contents of src/ and /home/, /home/ pointing
to contrib/.  I'll live with that, that's so much better than nothing
working locally.  Thanks for all the pointers, Andres.
