I brutally applied the post-v0.8.0 patches stolen from b4.git over my
local distro b4 files.

And was able to apply the triple:

$ git log --oneline --no-merges
5.17.0-rc6-1-amd64-clang13-lto..5.17.0-rc6-2-amd64-clang13-lto
96a4222bdd4c (for-5.17/kbuild-std_gnu11-arndb-20220301) Kbuild: use
-std=gnu11 for KBUILD_USERCFLAGS
c4e8cef401a8 treewide: use -Wdeclaration-after-statement
6a7cc105b238 Kbuild: move to -std=gnu11
