Generate the kernel config choice, rather than having it hard-coded:
- change the menu label from 'Target OS' to 'Operating System',
- bare-metal is a kind of kernel (OS), rename to 'bare-metal' from 'none',
- update the kconfig.mk to generate the kernel choice entries,
- update glibc&eglibc kernel version option accordingly.
Update the debug & tools confiog file generation to match with arch & kernel.
Print terse command lines when building in kconfig/ (a-la Linux kernel).
Fix the makefile rules in kconfig/kconfig.mk to be /simple/ rules.

       It is highly recommended that 'make check' is run against the newly built

       GMP library. See http://gmplib.org/
