Motivation for this change
compiler-rt (and as a result clang) can't be build for i686 (as noticed here: #99984).
The patch adds the required variables and should result in the same behavior as in the nixpkgs-llvm10. It essentially forces to use i386 buildins when using i486, i586 or i686, which are not supported.
Fixes #100392
