I could, but that would defeat the purpose somewhat.

I believe "make headers_install" isn't "this is what userspace *has* to 
get from the kernel" (which is, after all, the null set -- people wrote 
C libraries for DOS for example), but "this is what the kernel provides 
to userspace."  It's up to userspace to use it or not, depending on the 
suitability for any one particular userspace.
