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.
