make-kpkg cross compile

[Emanuel Schmid <emanuel.schmid@grob.org>]

hello

i'm trying to cross compile a sparc kernel on an i386 with make-kpkg.
setting KPKG_ARCH=sparc and CROSS_COMPILE=sparc-linux (according to man
make-kpkg) and running make-kpkg produces the following warning:

--------
dpkg-architecture: warning: Specified GNU system type sparc-linux does not
match
 gcc system type i386-linux.
--------

if i set CC=sparc-linux-gcc this warning disappears, but the compiled
kernel does not run (which very likely is not the problem of make-kpkg as
"make ARCH=sparc CROSS_COMPILE=sparc-linux-" does not result in a running
kernel either)

does anybody else know this problem?
is this a bug or am i to tired?

thanks
emanuel
