Regressions on i386 the defconfig builds failed with clang-20
and gcc-13 the stable-rc 6.6.81-rc2.

First seen on the
 Good: v6.6.78
 Bad: v6.6.78-442-g8f0527d547fe

* i386 build
  - clang-20-defconfig
  - clang-nightly-defconfig
  - gcc-13-defconfig
  - gcc-8-defconfig

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

Build regression: i386 microcode core.c use of undeclared identifier
'initrd_start_early'
