Remove autotools-generated files

Remove autotools-generated files from version control.  These can be
regenerated via the bootstrap script.

The bootstrap script does not set PATH because the pathname for
autoreconf varies across platforms.  For example:
- /usr/bin/autoreconf (Linux)
- /usr/local/bin/autoreconf (FreeBSD and OpenBSD)
- /usr/pkg/bin/autoreconf (NetBSD)
