Subject: next-20250723 arm atags_to_fdt.c undefined reference to `__sanitizer_cov_stack_depth'

Regressions noticed while building arm builds with gcc-13 and gcc-8
toolchains on the Linux next-20250723 to next-20250725 tags.

First seen on the Linux next-20250723
Good: next-20250722
Bad:  next-20250723 and next-20250725

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

## Build regressions
* arm, build
