[Linux-v4.18-rc6] modpost-errors when compiling with clang-7 and CONFIG_DRM_AMDGPU=m

Hi,

when compiling with clang-7 and CONFIG_DRM_AMDGPU=m I see the following...

"scripts/mod/empty.o" ]; then ./scripts/recordmcount
"arch/x86/boot/compressed/misc.o"; fi; fi;

For now I have disabled CONFIG_DRM_AMDGPU=n.

Do you need further informations?
