This is wrong too, especially in cases like this. It keeps you from
using new drivers (fb, v4l, etc.) available when you get a new kernel.
And none of this has anything to do with libc. In fact, glibc is
supposed to be kernel-header-independent, so kernel headers should
only be used to getting the structs to use with ioctls, ioctl numbers,
etc. -- not any syscall interfaces.

FYI, I have used a system with symlinks to /usr/src/linux for 6 years
now with no problems whatsoever, so I have no idea why the distro
people think you have to use the same kernel headers you compiled libc
with...
