Subject: next-20250730 x86, s390, riscv gcc-8 hardening.config vmlinux symbol
 `.modinfo' required but not present

Regressions while building x86, S390 and riscv64 with hardening.config on the
Linux next-20250730 and next-20250731.

Build pass with gcc-13 with hardening.config fails with gcc-8

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

First seen on the next-20250730
Good: next-20250729
Bad: next-20250730
