[Naresh Kamboju]

Regressions on arm64 lkftconfig failed with gcc-12 on the Linux next-20250507.

First seen on the next-20250507
 Good: next-20250506
 Bad:  next-20250507

Regressions found on arm64:
  - build/gcc-12-lkftconfig-graviton4

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

Build regression: arm64 local label `"3" (instance number 1 of a fb
label)' is not defined
