Linus has spoken. /usr/include/{linux,asm} must not be a symlink that
points to kernel code that is updated. glibc must contain the linux
and asm files that were used to build glibc and those files must not
change until you change glibc. glibc must take a copy of the kernel
headers at glibc build time or (much less desirable) it can symlink to
a set of kernel headers that are guaranteed to never change.

Having glibc linking to some random set of kernel headers is a recipe
for disaster. kbuild 2.5 deliberately handles the asm symlink
differently from the old kbuild system, to detect and correct broken
installations.
