Fix warnings that appear during the build of the llvm package

The package redefines %optflags on i686 and s390x, so the
%__build_for_lang_* macros are no longer expanded, triggering
a warning from RPM (“%__build_for_lang_any defined but not
used within scope”).  Clang warns about -Wno-complain-wrong-lang
with -Wall, so the warning option is suppressed for
"%toolchain" != "gcc".
