Actually, on re-reading my patchset, I was tackling a different issue
for VPATH builds.  I think your patch is correct after all, just that we
still need my patches as well once they get reviewed.  BUILT_SOURCES
does not cause the file to be distributed, but does cause it to be built
earlier in the process, which is what we need since compilation of other
files depends on it existing.
