Subject: [PATCH 18/54] Make sure to reset file attributes for generated

 build-id directories.

[Note this patch is currently being tested in Fedora. See bug below.]

When creating the build-id directories we should reset the file attributes

to the defaults. Otherwise if the file list contained an %attr or %defattr

the directories would come out with the wrong mode.

Includes a testcase based on a spec by Igor Gnatenko that fails before

and Check that build-id directories are created with the right permissions

even if the spec file sets attrs explicitly.
