[PATCH v2 0/4] Delete temporary files under /tmp

[H.J. Lu]

Delete temporary files under /tmp generated by "make test", instead of
leaving them behind:

1. Call support_delete_temp_files to delete temporary files before exit in
support_subprocess.
2. Update tst-fopen-threaded.c to call support_create_temp_directory to
create a temporary directory and open "file" in the temporary directory,
instead of using /tmp/openclosetest and leaving it behind.
3. Update tst-freopen4-main.c to call support_capture_subprocess with
chroot, which makes temporary files inaccessible, so that temporary files
can be deleted.
4. Update tst-env-setuid.c to delete LD_DEBUG_OUTPUT output, instead of
leaving it behind.

These fix BZ #33182.

H.J. Lu (4):
  Delete temporary files in support_subprocess
  tst-fopen-threaded.c: Delete temporary file
  tst-freopen4-main.c: Call support_capture_subprocess with chroot
