Don't do that.  The name 'core' is reserved for core dump regular files,
and creating a directory by the same name will interfere with years of
traditional handling of regular files for core dumps.

This is evidence of you violating common assumptions by creating a
directory named 'core'.

Yep.  You need to pick a different name.  Autoconf is probably not going
to change to work around your one-off naming.
