I found the way out (but with a caveat...) - you add 'subdir-objects' to
the AM_INIT_AUTOMAKE line in configure.ac (portable back to RHEL 5's
automake 1.9).  But in doing so, automake then tries to create a
directory named:

./src/$(srcdir)/remote/.deps

among others (yes, that's the literal directory name it created).  Which
means we have a bug in our (ab)use of BUILT_SOURCES - we are can't ship
generated .c files as part of the tarball and ALSO require that they be
built first but into the srcdir.  And since these are the very files
that are already causing rpcgen grief on non-Linux platforms, we
definitely still want to ship the generated .c, even if we don't store
the generated files in git.

Well, I now have my environment set up to reproduce the problem with
automake 1.14, and will hopefully have patches soon.
