First: try the RPMs. Obviously this will be easier for you.

No! These are kernel headers from glibc-kernheaders (or kernel-headers
in RH 7.[012]) package, which were used to build glibc. They are to be
used for building regular software, not kernel modules. That's why you
get the error below.

Apparently you do not understand the above messages.
Since kernel 2.4.0, current running kernel headers (which are required
to build this kernel module) are in /lib/modules/`uname -r`/build/include
and that's the directory you should put in the Makefile.
