delete_old_cluster.sh is generated within tmp_check/ in a non-VPATH
build:
$ cd src/bin/pg_upgrade/ && make check
$ find . -name delete_old_cluster.sh
./tmp_check/delete_old_cluster.sh
$ git grep chdir -- *.pl
t/002_pg_upgrade.pl:chdir ${PostgreSQL::Test::Utils::tmp_check};

Or you have a workflow where you do a "make clean" after running the
tests on a past stable branch?  This would leave behind
delete_old_cluster.sh, especially if the cleanup is triggered on
HEAD.  With each branch taken in isolation, there is no need for a
.gitignore entry.  (FWIW, I just use a worktree these days in my flow
of patching across multiple stable branches.)
