[PATCH 0/2] selftests/lib.mk: LLVM=1, CC=clang, and warnings

[John Hubbard]

The kselftests may be built in a couple different ways:
    make LLVM=1
    make CC=clang

In order to handle both cases, set LLVM=1 if CC=clang. That way,the rest
of lib.mk, and any Makefiles that include lib.mk, can base decisions
solely on whether or not LLVM is set.

Then, build upon that to disable a pair of clang warnings that are
already silenced on gcc.

Doing it this way is much better than the piecemeal approach that I
started with in [1] and [2]. Thanks to Nathan Chancellor for the patch
reviews that led to this approach.
