bisect-runner.pl needs to set @paths correctly on 32 bit Linux

Without this, Configure may fail prior to commit 1cfa4ec74d4933da (which
added the 'ignore_versioned_solibs' logic), because bisect-runner.pl's code
to set libs relies on successfully finding at least one library to pass to
./Configure with -Dlibs=

miniperl and perl should now build back to perl-5.000 on 32 bit Linux.
test_prep may not work, as early versions of DB_File.xs will fail if a
new db.h is found.
