commit 885480b084696331bea61a4f7eba10652999a9c1 upstream. Currently, -Wunused-but-set-variable is only supported by GCC so it is disabled unconditionally in a GCC only block (it is enabled with W=1). clang currently has its implementation for this warning in review so preemptively move this statement out of the GCC only block and wrap it with cc-disable-warning so that both compilers function the same.
