Problema de dependência do Buildroot criando novo kernel - libelf-dev

Question

Estou atualizando para o kernel 4.14.73 usando buildroot, parece que este novo kernel tem uma dependência de libelf-dev quando recebo este erro:

Makefile:953: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop.
make[1]: Leaving directory '/media/vmpart/kernel-upgrade/buildroot/output/build/linux-4.14.73'
make: *** [/media/vmpart/kernel-upgrade/buildroot/output/build/linux-4.14.73/.stamp_compiled] Error 2

Eu verifiquei o makefile e esta é a área em questão:

ifdef CONFIG_STACK_VALIDATION
      has_libelf := $(call try-run,\
            echo "int main() {}" | $(HOSTCC) -xc -o /dev/null -lelf -,1,0)
      ifeq ($(has_libelf),1)
        objtool_target := tools/objtool FORCE
      else
        ifdef CONFIG_UNWINDER_ORC
          $(error "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel")
        else
          $(warning "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel")
        endif
        SKIP_STACK_VALIDATION := 1
        export SKIP_STACK_VALIDATION
      endif
    endif

Em particular, esta verificação está falhando:

has_libelf := $(call try-run,\
            echo "int main() {}" | $(HOSTCC) -xc -o /dev/null -lelf -,1,0)

Eu então adicionei o pacote elfutils que eu vi deveria ter esses devtools (isso é instalado mas minha compilação não reconhece que é), eu fiz minha compilação do Linux ter uma dependência de host-elfutils (assim como link ) e construído com sucesso host-elfutils-0.170 , no entanto, eu ainda recebo o erro, o que exatamente é o cheque que espera nesta linha, precisa do .so para estar em algum lugar em particular?

has_libelf := $(call try-run,\
            echo "int main() {}" | $(HOSTCC) -xc -o /dev/null -lelf -,1,0)

Estou usando uma versão mais antiga do buildroot, então talvez eu precise fazer alguma coisa no meu arquivo de forma diferente?
