Push the calculation of the tuple's kernel part down to kernel's build scripts:
- update the kernel script's API with the function CT_DiKernelTupleValues
- update doc accordingly (also with the architecture change, missing in the previous commit)
- small clean-up in the main script, remove useless test

 Original patch from H.J. Lu, as reported there:

 http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html

 fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

 The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
