If you really want to be sure, I'd say you have to contact Mariusz Mazur 
(the maintainer of the linux-libc-headers) about it, but it seems like a 
sane way to do.

Just did a make prepare on a vanilla kernel tree, it seems it does the 
following:

aschuring@golem:~/work/linux-2.6.7 > make defconfig ARCH=sh
[...]
aschuring@golem:~/work/linux-2.6.7 > make prepare ARCH=sh
 Making asm-sh/cpu -> asm-sh/cpu-sh3 link
 Making asm-sh/mach -> asm-sh/unknown link
make[1]: `include/asm-sh/machtypes.h' is up to date.

Which with -n translates to:

ln -sf cpu-sh3 include/asm-sh/cpu
ln -sf unknown include/asm-sh/mach

So you were correct. You might run into a missing mach-dir later, also. I 
guess the sanitized headers need some postprocessing for some architectures, 
though this might be difficult to incorporate in crosstool.
