[PATCH v2 2/3] BaseTools/tools_def CLANG38: add -Wno-unused-const-variable

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

Commit 8b6366f87584 ("BaseTools/GCC: set -Wno-unused-const-variable
on RELEASE builds") suppresses warnings about unused constant
variables in RELEASE builds when building with GCC, given that they
break the build under our warnings-as-errors policy.

Do the same for CLANG38.
