 Description: use KBUILD_CFLAGS and (KBUILD_)LDFLAGS
- allows building a amd64 kernel module with i386 user space
- .
- skip -Werror=* since that breaks how conftest.sh detects stuff
- .
  skip $(GCC_PLUGINS_CFLAGS): fixes build failure when a kernel
  is built with CONFIG_GCC_PLUGINS, CONFIG_GCC_PLUGIN_STRUCTLEAK
