Debian is only the first one, the others will follow. The point is to
ensure that application programs can be compiled with a set of headers
that matches those headers the installed libc was compiled with and still
being able to compile a new kernel version.
The kernel compilation never touches /usr/include/linux whereas the
compilation of an application program never touches
/usr/src/linux/include/linux. But if you have /usr/Include/linux symlinked
to /usr/src/linux/include/linux and install a newer kernel source, chances
are that the compilation of a user program will break because the headers
don't match those your libc was compiled with. The same holds for
/usr/include/asm and /usr/src/linux/include/asm respectively.
There were a couple of different attmepts to solve the problem in Debian
which let to the current solution. I read a detailed documentation about
that some time ago but I'm sorry to say I nca't remember where. There
is however some documentation in /usr/doc/libc6/README.Debian.gz which
tells you what to do if you really need to compile application programs
with a different set of headers than those supplied by libc6-dev.
