From: Bruce Ashfield <bruce.ashfield at gmail.com>

The 5.3 kernel has two changes that require tweaks to the minimal
kernel-devsrc package.

- 4ce97317f [x86/purgatory: Do not use __builtin_memcpy and __builtin_memset]

  This change removes the need for arch/x86/purgatory/string.c and
  instead reuses a copy in arch/x86/boot/compressed/, so we can't copy
  the file anymore. To support older kernels, we make the copy survive
  the non-existence of the file.

- b1663d7e [docs: Kbuild/Makefile: allow check for missing docs at build time]

  This change adds the sourceing of Documentation/Kbuild to the top
  level Kbuild file. So we now leave the copy of Documention/'s Kbuild
  in the devsrc.
