Kees Cook dba8725f4c BACKPORT: FROMGIT: kbuild: mkcompile_h: Include $LD version in /proc/version ... When doing Clang builds of the kernel, it is possible to link with either ld.bfd (binutils) or ld.lld (LLVM), but it is not possible to discover this from a running kernel. Add the "$LD -v" output to /proc/version.
