No, it isn't, and it's really, really, perplexing.  Here's what I've
tracked down.

In autoconf.mk, there are the rules I quoted above.  Now, if I change
$(DEB_BUILDDIR) to the explicit directory, all works fine.  But the
variable appears to be expanded incorrectly: $(DEB_BUILDDIR) appears
to have the value 'build', as far as the output of make --debug=v
gives (it searches for the file build/config.status).  But, when I put
in a command "@echo DEB_BUILDDIR=$(DEB_BUILDDIR)" to see what's going
on, it gives the correct value.  And it I create a dummy file called
build/config.status in the top source directory (the one containing
the debian/ directory), all works fine once more.  It's almost as
though make (version 3.80-2) has a bug....

Weird or what?
