strip can be coming from binutils or from llvm
in some cases llvm-strip can fail on kernel
Subprocess output:aarch64-yoe-linux-llvm-strip: error: Link field value 28 in section .rela.dyn is not a symbol table
This helps in selecting which strip is used when building kernel

This helps in switching toolchains cleanly for kernel build
between gcc and clang
Currently, some kernels allow building with clang but not all
the distro might use clang as default system compiler but kernel
may demand gcc which is provided via KERNEL_* variables, however
kernel does use OBJCOPY at places during build and it maybe set
to use llvm objcopy when using clang. That should be a deliberate
setting when clang is used for kernel as well, otherwise it should
use binutils provided objcopy

Improve the fatal error message of the yocto-kernel-tools symbol_why.py
and shows the command that generate the error as it can help understand
the root cause of the error.

Move classes to classes-global or classes-recipe as appropriate to take
advantage of new bitbake functionality to check class scope/usage.
