kbuild: uapi: use -fsyntax-only rather than -S
The UAPI header tests are checking that the generated headers do not have syntax errors. There's no need to run the rest of the compilation pipeline after semantic analysis has run. Replace -S -o /dev/null with -fsyntax-only. Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
