configure: have bash_absolute and perl_absolute always defined
Since set -u is used, without bash or perl, configure would fail. This has gone unnoticed as (almost) everyone always had both bash and perl installed (and in $PATH). Thanks to FreeBSD ports this bug became visible; this change is verbatim copy of `patch-configure` in FreeBSD ports tree.
