include: kernel-build: pass pkg-config overrides to kernel build
Pass suitable pkg-config overrides to the kernel build process in
order to let our pkg-config wrapper discover libraries provided
by tools/.
This mainly affects the use of libelf which is required for the
CONFIG_STACK_VALIDATION features. So far, the build system either
silently used host system libraries or kbuild simply disabled the
feature due to the lack of a suitable libelf.
