crosstool-ng/scripts/build/kernel/linux.sh
Yann E. MORIN" 1c625d676c 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
