You _really_ don't want to do this.

The kernel-headers package contains the headers used to build glibc. The
.h files live in /usr/include/{asm,linux}.
The kernel-headers package is not upgraded when the kernel is upgraded.
The headers used for the current kernel are in
/usr/src/linux-{kernel-version}/include/
(A symlink should exist, /lib/modules/`uname -r`/build, which points to
the installed kernel-source.)
Things should compile fine just the way they are.
