483c6067eb module.bbclass: add KBUILD_EXTRA_SYMBOLS to install
Symbols are used during install as well, adding KBUILD_EXTRA_SYMBOLS enables
successful installation.

0ef2e5081b kernel: Add kernel specific STRIP variable
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

43a4d45f51 kernel: Add kernel specific OBJDUMP
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

fd1517e2b5 classes: Update classes to match new bitbake class scope functionality
Move classes to classes-global or classes-recipe as appropriate to take
advantage of new bitbake functionality to check class scope/usage.
