Autoheader is indeed always run with PWD = top_builddir.

I doubt it.  I've certainly used it with srcdir != builddir.

It's likely that assumptions change depending on which program is

Anyway, I've just realized that your change affects only aclocal,
autoconf, autoheader and automake emulations, and all of these are
always run off top_srcdir, so the change is safe, even though it sets
a precedent that might lead others to conclude missing is always run
off top_srcdir (since the test for is always done).  I'd
appreciate a comment before the test explaining why it is safe to do
the test there even though missing isn't always guaranteed to run in
the directory containing configure.{in,ac}.
