Subject: fortify: drop Clang version check for 12.0.1 or newer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7d354f49b8d6b29208beb6233ebd197c7570a88b;p=linux.git

fortify: drop Clang version check for 12.0.1 or newer

Now that the minimum supported version of LLVM for building the kernel has
been bumped to 13.0.1, this condition is always true, as the build will
fail during the configuration stage for older LLVM versions.  Remove it.
