[PATCH 03/11] x86: Drop stack-alignment plugin opt

[Nathan Chancellor]

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 13.0.1, the inner ifeq statement is always false, as
the build will fail during the configuration stage for older LLVM
versions.

This effectively reverts part of commit b33fff07e3e3 ("x86, build: allow
LTO to be selected") and its follow up fix, commit 2398ce80152a ("x86,
lto: Pass -stack-alignment only on LLD < 13.0.0").
