Since LLVM commit 3787ee4, the '-stack-alignment' flag has been dropped [1], leading to the following error message when building a LTO kernel with Clang-13 and LLD-13:

ld.lld: error: -plugin-opt=-: ld.lld: Unknown command line argument 
'-stack-alignment=8'.  Try 'ld.lld --help'
ld.lld: Did you mean '--stackrealign=8'?

It also appears that the '-code-model' flag is not necessary anymore starting with LLVM-9 [2].

Drop '-code-model' and make '-stack-alignment' conditional on LLD < 13.0.0.

This is for linux-stable 5.12. Another patch will be submitted for 5.13 shortly (unless there are objections).

This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.
