#     kbuild: tell sparse about the $ARCH
#     
#     Sparse uses the same executable for all archs and uses flags
#     like -m64, -mbig-endian or -D__arm__ for arch-specific parameters.
#     But Sparse also uses value from the host machine used to build
#     Sparse as default value for the target machine.
#     
#     This works, of course, well for native build but can create
#     problems when cross-compiling, like defining both '__i386__'
#     and '__arm__' when cross-compiling for arm on a x86-64 machine.
#     
#     Fix this by explicitely telling sparse the target architecture.
