1)
Regressions on arm64, 390 tinyconfig, allnoconfig builds with clang-20
and gcc-13 on the stable-rc 6.14.

2)
Regressions on arm, arm64 rustclang-lkftconfig-kselftest builds with
clang-20 and gcc-13 on the stable-rc 6.14.

First seen on the 6.14.2-rc1
Bad: v6.14.1-732-gabe68470bb82
Good: v6.14.1

* arm64 and s390, build
 - build/gcc-13-tinyconfig
 - build/clang-20-tinyconfig

* arm and arm64, build
 -  build/rustclang-lkftconfig-kselftest

Regression Analysis:
- New regression? Yes
- Reproducibility? Yes

Build regression: arm64 s390 tinyconfig undefined reference to
`dl_rebuild_rd_accounting'
Build regression: arm64 arm rust pci.rs cannot find type `Core` in
module `device`

Reported-by: Linux Kernel Functional Testing <lkft@...aro.org>
