Arnd Bergmann 9827504ba7 kbuild: hdrcheck: fix cross build with clang
[ Upstream commit 02e9a22cee ]

The headercheck tries to call clang with a mix of compiler arguments
that don't include the target architecture. When building e.g. x86
headers on arm64, this produces a warning like

   clang: warning: unknown platform, assuming -mfloat-abi=soft

Add in the KBUILD_CPPFLAGS, which contain the target, in order to make it
build properly.

See also 1b71c2fb04 ("kbuild: userprogs: fix bitsize and target
detection on clang").
