Just a separate build directory. Specifically, I'm hitting the errors with

 make -C build-amd64 M=drivers/gpu/drm

Generated headers such as r420_reg_safe.h reside in the build directory, so source files in the source directory can't find them without an explicit search path. Are you saying that should get added automagically somehow?

FWIW, this is pretty common in the kernel according to git grep.
