Subject: [GIT PULL] Clang features fix for v5.13-rc7

Hi Linus,

Please pull this additional Clang feature fix for v5.13-rc7. It seems
Clang has been scrubbing through the missing LTO IR flags for Clang 13,
and the last of these "only with LTO" flags is fixed now. I've asked
that they please consider making these changes in a less "break all the
Clang kernel builds" kind of way in the future. :P

Thanks!

-Kees
