Yep :). I pushed a fix to that now.

I wonder if perhaps find's behaviour might have changed at some point?

I'm personally not excited about working on fixing this, but if somebody else
wants to spend the cycles to make this work reliably...

It's certainly interesting that we have some code worrying about symlinks in
configure.ac:
# prepare build tree if outside source tree
# Note 1: test -ef might not exist, but it's more reliable than `pwd`.
# Note 2: /bin/pwd might be better than shell's built-in at getting
# a symlink-free name.

But we only use this to determine if we're doing a vpath build, not as the
path passed to prep_buildtree...
