Kallsyms is arch-specific, isn't it? So shouldn't that be
$(CROSS_COMPILE)kallsyms?
How does one go about making non-native kallsyms?
The 2.5 kallsyms doesn't break cross-compilation, does it?

kallsyms does not build in cross compile mode. There are hacked up
versions of kallsyms for specific cross compile environments and the
user selects them by make KALLSYMS=... I was going to make modutils
fully cross compile compatible but now it has moved into the kernel
there is no point. Pity that the kernel version is incomplete.

Google for kallsyms i386 ia64.
>The 2.5 kallsyms doesn't break cross-compilation, does it?
No, but neither does it support the section data that is needed for kdb
(and possibly kgdb). The removal of section data in 2.5 is one of the
reasons that I no longer do kdb patches for 2.5 kernels. If you want
to destroy kdb for 2.4 kernels as well, go ahead and use the 2.5
kallsyms. It will actually make my life easier if I no longer have to
support kdb on standard kernels.
This patch does not break cross compilation either. It is a
restriction that you cannot use kallsyms in cross compile mode unless
you have a version like kallsyms_i386_ia64.
