Kbuild fixes for 7.0 #1

Hi Linus,

Please pull this first round of Kbuild fixes for 7.0. The majority of these changes are fixes for commit 62089b804895 ("kbuild: rpm-pkg:
Generate debuginfo package manually"), which came in at 6.19-rc8 (not 6.19-rc1 like the merge commit in this pull request says but I realized too late and did not want to rebase). I thought that change was sufficiently tested but I guess I only used the most recent version of rpm.

Due to the backmerge of the 7.0 changes in v6.19 to pick up that aforementioned rpm-pkg change, the 'git request-pull' diff stat was quite large, so I manually generated the one below with

  $ git diff --stat df989b01b5f9..kbuild-fixes-7.0-1

which should be accurate with what is actually merged into your tree. Please let me know if that is a problem.

Cheers,
Nathan

This does not make too much sense reading it back. It probably should have been something like:
