The "copy-in" step from regular source tree is a definite ouch. Do you have 
any clue as to why it is missing from the linux-libc headers? You might want 
to file a bug report against linux-libc-headers for it, I'm not sure how 
much attention sh3 gets...

I posted a patch for crosstool a few days ago which effectively does the 
steps you described above, do you think it is worth it if we would extend 
that patch to create the cpu->cpu-sh{2,3,4} link too? I'm a little hesitant 
myself, because we would be redoing (part of) the kernel's make prepare, but 
if that is the only way to get crosstool build a toolchain with sanitized 
headers for sh3...

Maybe other arches need things like this as well?
